#ssl certificate error

Publication reports improved search visibility and site authority within days of transition Presence News has confirmed the successful migration of its website to a new hosting provider following what the organization described as “ongoing and unresolved technical issues” with its previous provider, Kinsta. The transition, completed approximately two days ago, comes after multiple reported…

What is “Your Connection Is Not Private” Error?

The websites that are running over HTTPS shows “Your connection is not private” error. The place where the site is hosted gets a message by the browser when you visit a particular website. For ensuring that the website certificate is up to current privacy standards, the browser needs to install the validated certificate on the website. The certificates also checked by a certificate authority for the decryption of the certificate.

The browser will always prevent you from reaching that particular website whose certificate is not valid. This is an exciting feature that is already in built-in web browsers for protecting users. If the certificate on the website is not properly set up, that means that the user’s data is not encrypted and it is also not safe to visit that site. So these unsafe sites show a message by the browser that “Your connection is not private.”

SSL CONNECTION ERROR MEANING

Secure Socket Layer (SSL) certificates provide privacy and encryption over HTTPS connections. The security barriers that are used for the safety and protection of the data on authorize connection is HTTPS. When the browser doesn’t have a way secure way to protect your data from the unsafe site then it will show SSL connection error. The browser will try to stop you from accessing the website if it will feel that the particular site is unsafe and not have a secure connection. There are some reasons due to which SSL connection error appears:

– Missing or expired certificate

– Non-updated browser

– Antivirus and date or timing settings are wrong

– Issue in the server

HOW “Your Connection Is Not Private” LOOKS ON DIFFERENT BROWSERS?

Depending on the web browser you are using, there are variations or looks of this error. The configuration is also differing for different web browsers.

Google Chrome

Google Chrome will take you to a separate page named privacy error when this error message shows to the user. On that page, a significant exclamation point in red color appears and also “Your connection is not private” message visible on the page. This will protect your information and tell you about the problems like attackers that may hack your credit card details, passwords, and messages.

This will highly aware of you and protect you from not visit that particular unsafe website but even then if you want to visit that site then it will show an advance option. Click on that Advance option while going back to the previous page and attempt to visit the website.

Microsoft edge

Microsoft Edge shows the error that is almost similar to Google chrome. It says that “Your connection is not private”.

HOW TO FIX “Your Connection Is Not Private” ERROR?

Sometimes you might even get confused about how to begin and deal with this error. Typically, there can be 2 significant reasons for appearing the error: one is the issue from the client-side and others can be a certificate problem on the website. There are different ways discussed below through you can fix this error.

Reload the page

This might seem to be obvious and the first thing you should try. Reload the page again when you face the error “your connection is not private.” Simply close and re-open the browser and again search for the site which you want to visit. This may solve the issue sometime when the owner of the website is reissuing the SSL certificate or browser is having some problem.

Try Incognito Mode

In Incognito mode, the data will be saved to try this and visit that particular site. If the website is seriously having some security issues, it will not open in Incognito mode.

Check date and time

Check your system date and time. The site can also show the error if your system date and time is not updated. The information will appear on the previous date and time that is updated on your system.

Clear cache and cookies from the browser

When you search something then at that time the browser stores caches and cookies that can take up a huge space of your hard disk. The computer will become slow down. For solving this issue, you can go to your browser settings and clear all the caches and cookies. This will speed up the connection and also may explain the “your connection is not private” error.

Check Wi-Fi connection

The public Wi-Fi may not be safe and secure as some public Wi-Fi does not run HTTPS and has a poor configuration. Try not to use public Wi-Fi for searching for anything related to information that can be hacked. Always use your private and safe Wi-Fi connection. This will secure and encrypt your information. If it’s very urgent and you don’t have any option rather using public Wi-Fi, then you can hide your information by using Virtual Private Network (VPN). This will hide your identity and also protect you from traffic.

Check antivirus

If there is an antivirus connection in your system, then search for its update. The antivirus can override your network because “your connection is not private” error appears. This issue can be resolve by disabling the antivirus for some time.

CONCLUSION

The first version of Google’s web browser Chrome was launched in 2008. The application leads a very high success in the coming years after launched and gives tough competition to Internet Explorer, Firefox, etc., web browser applications. Its rapid success is its marketing strategy that was done by its own already popular brand name Google. The browser’s performance is excellent even though it may show some error many times that leave its users confronted with cryptic messages.

When you visit some website and it shows an error message “ERR_CONNECTION-CLOSED” then this means that the browser closed your connection to the website. This fixing of this error is very complex tasks because Chrome does not cause that particular error.

What does ERR_CONNECTION_CLOSED mean?

Sometimes when you visit a website an error appears on your screen “ERR_CONNECTION_CLOSED.” This is the way of Chrome for informing the user that transferring of data that needs to establish a connection is interrupted. This error also indicates that the connection between browser and server is closed.

How to fix ERR_CONNECTION_CLOSED error?

There may be several different solutions for resolving the ERR_CONNECTION_CLOSED error. This will emphasize the real and exact problem of the error. The details of why connection interruption happens are not revealed. If the reason for connection interruption not revealed, then there is no main and perfect solution for fixing this error. There can be various solutions that can be tried for resolving the ERR_CONNECTION_CLOSED error.

1. Check internet connection and restart the router

Before you will try deep and technical methods for resolving ERR_CONNECTION_CLOSED error, check your internet connection first. In the network connection settings of your system, you can easily identify your internet connection status. If it’s not connected properly then you can restart your router and connect again. This may be the problem of the error.

2. Reset network settings

The error message ERR_CONNECTION_CLOSED problem may also occur due to some network connection issues in your system’s TCP/IP setup. This problem can be solved by resetting the settings of TCP/IP stack from their original state.

The one thing you need is administrator rights and command-line tool Netshell and this has been installed since Windows 2000 as default. This can be done by first accessing the start menu and entering the term ‘cmd’ in the search bar. Then right-click on cmd application and select ‘Run as administrator.’

3. Disable the proxy server and VPN connection

Proxy and VPN connection offers you different possibilities in their way of remaining anonymous during your time on the internet. Both solutions are fully and actively participating in the data transfer process.

This can be the reason of causing complications and showing the error message ERR_CONNECTION_CLOSED. At least for testing purposes deactivate bridging techniques and don’t use it in case of VPN.

4. Clear DNS cache

One of the essential mechanisms of the internet is the resolution of the DNS server name. Whenever a particular website has accessed the conversion of domain address into their numerical counterparts takes place. When both DNS servers and browsers create address entries, then it is called DNS cache.

The loading time becomes faster but can also cause unwanted errors like ERR_CONNECTION_CLOSED. This error can be resolved by flushing out the DNS caches from the system. You need to empty the address cache.

5. Change DNS server manually

Not just DNS cache is the problem of showing the error message. Other issues can also cause the error. The connection may also have interrupted and Chrome shows error message ERR_CONNECTION_CLOSED if the server’s availability is limited or server is completely down.

The address of the DNS server usually obtains automatically. However, this can also be done manually and thus transferring the name resolution task to another server to fix the “ERR_CONNECTION_CLOSED” message.

6. Check firewall and antivirus software

Due to numerous attackers’ danger on your daily activities of the web, today’s time must protect the system from antivirus. The firewalls, antivirus software, etc., does a very excellent job but even then these tools are not infallible. The error ERR_CONNECTION_CLOSED can be caused by incorrect configurations, software errors, or outdated program files. This can be resolve by updating the software of your system or deactivate antivirus or firewall software temporarily.

7. Update or reinstall chrome

WHAT IS THE MEANING OF SSL/TLS?

The full form of SSL is Secure Sockets Layer. It allows a secure connection between a website and a web browser. The SSL consists of various versions like 1.0, 2.0, 3.0 which improves the quality continuously. The technology of SSL is deprecated now and TLS entirely replaces it. Transport Layer Security is referred to as TLS. It provides the security of the data similar to SSL. The people should start using this new version of SSL that is named as TLS.

WHAT IS SSL/TLS HANDSHAKE?

The beginning of every SSL/TLS certificate starts with a handshake. This is the negotiation between two parties in which the proceeding details of work are discussed. How cipher suite encrypts their communication and also how they can use this for verifying server and establishing a secure connection? A handshake decides this. This process is very complex and you will not be able to see precisely as all this work happens in the background.

OPERATE SSL/TLS HANDSHAKE

When the client and the server both agree and ready to start communication with each other through secured and encrypted SSL/TLS medium with data security then this process lye under Handshake SSL/TLS. The client and server can develop a secret communication key for encryption when they meet for the first time.

A card number with a random set of symbols establish at the time of establishing of secure connection and afterwards sent it to the server. By using the special key receiving party can encrypt the message. If any cyber-attack takes place for hacking the information, then they can only see the set of symbols and nothing else.

The SSL/TLS handshake is not only used for bank servers but it is providing protective security and privacy so that the information on the internet will be confidential and cannot spread anywhere else.

HOW TO FIX SSL/TLS HANDSHAKE FAILED ERROR?

On the connection parameters, both the client and the server should agree for exchanging data such as verification of valid certificates, transferring data management, etc. This is not a very easy and simple process; instead it is a very complicated and multi-level process.

Even if only in one level of the process some disturbance came or it becomes failed then the whole SSL/TLS handshake failed and shows an error.

Possible Causes and Solutions of SSL/TLS Handshake Failure

Troubleshooting for the website owner

Mismatching of Protocol

In order to ensure the proper protection and security, SSL and TLS protocol versions are being improved with better features and remove the most vulnerable segments. Some of the people are still using the outdated version. These versions operate unsafe cipher suites and short keys.

The mobile apps or software which not updated on time, this issue comes in those mainly. The main reason for the error in the SSL/TLS handshake may be that both the client and the server support the protocol version. If you use the latest version, then this problem of error will not come while in most cases the client-server is of outdated protocol and in this case, the server will not be able to resolve the issue.

Cipher mismatch

The first and main step is creating a common ground for the communication of the client and the server. A cipher suite is used for this purpose and identifies a secure connection. At the beginning of SSL/TLS handshake a list of latest available cipher suites will be provided by the client-server.

You may face SSL/TLS handshake errors when cipher matches not found. This is the common cause of the error. The encryption protocol is used in different fields with its standards and for banks as well as industries they create and approved on their demand. In this case, the only solution is of decreasing the level of security but this may make your connection unsafe.

Wrong SSL/TLS certificate

The hostname in your SSL/TLS certificate may be incorrect and this can be the reason for facing error in SSL/TLS handshake. For this first you need to check the hostname should match with cipher suite and if not then reissue your certificate.

Middle Man

The SSL/TLS handshake may also cause failure when a third party is trying to attack your information and hacking it. The variants of “Man in the Middle” are a lot such as API. You need to identify who is the Middle man due to which SSL/TLS handshake showing failure.

Troubleshooting for clients

Change or update your browser

As a rule, all browsers are updated with the TLS protocol but some browsers may use the outdated version of the TLS protocol. When you use a browser for banking purpose and if it is using an outdated version of TLS protocol then it will directly reject everything and not accept anything in the old version.

In this case, you need to change your browser. Also, the browser you are using may be not up to date so update it and then start using it. This will not show any error afterwards.

Deactivate your extensions

The SSL/TLS handshake error may also come because of your plugins. Try them to deactivate one by one.

Change Wi-Fi Password

The SSL/TLS handshake failure may also be a cause due to the publicly acceptable internet network. You need to change your Wi-Fi password and don’t share it with anybody.

Clear Cache and Cookies

Try to clear your device from cache and cookies. This may also show error and handshake failure.

Correct time and date in your computer

The data of the certificate is read by the server first and it verifies it if it’s valid or not. It will show the data invalid if your time zone is not correct on your computer. This will be the reason for SSL/TLS handshake failure. You need to update the correct time and date on your computer and make sure always that they will be correct.

Expired SSL certificate

In the present time, one of the most used and popular web browsers is Google Chrome. Almost the whole world depends on this web browser for searching for information. The experience will not always be smooth and good for you. Sometimes it happens that error or glitch will come which can also block the site altogether for you.

The DNS_Probe_Finished_NxDomain is the commonly faced error that shows on Google. This is one of the annoying and big pools of errors. Let’s first discuss what DNS is?

WHAT IS DNS?

Most people can remember various website names. But if you are not from an IT background then it would be strange for you that every website, in reality, has an IP (Internet Protocol) address. The DNS is the Domain Name System. The DNS is intermediate that connects the website URLs with its actual IP address.

By using human-friendly names, DNS helps in transferring of IP. It is a big advantage for the users as they can use any website at any time without remembering the IP address. The process that includes the DNS precursor and helps in finding out the actual IP address of various servers is known as DNS name resolution.

WHAT IS DNS_PROBE_FINISHED_NXDOMAIN?

Sometimes it happens that DNS will not be able to find the IP address or domain name which a user is trying to visit. This is the case that the website shows some error which is called DNS_PROBE_FINISHED_NXDOMAIN Error. In this NX Domain refers to non—existence domain. This whole error indicates the DNS lookup failure. At last, what Google chrome does, it will block the user from visiting the website anymore.

HOW TO FIX DNS_PROBE_FINISHED_NXDOMAIN ERROR?

Not only one but there are several ways to fix DNS_PROBE_FINISHED_NXDOMAIN error.

Solution – 1 – Flush DNS Cache

The previously visited site information, as well as IP address, is saved in the DNS cache. By this, we can clearly say that DNS_PROBE_FINISHED_NXDOMAIN error is because of this and shows the IP address outdated. You need to follow some steps for flushing out the DNS cache.

Step 1: First you need to click on the start button.

Step 2: Search for the Command Prompt option

Step 3: Select Run as administrator by right click

Step 4: New window open showing: ipconfig/flushdns

Step 5: Click enter after completing.

Solution – 2 – Release and Renew IP address

This is the same as the previous solution but this will clear DNS cache in more depth. Open the command prompt from the previous step and now follow command one by one:

Step 1: Release your current IP address by entering: ipconfig/release

Step 2: For full configuration of IP address use: ipconfig/all

Step 3: For resetting of the DNS cache use: ipconfig/flushdns

Step 4: For renewing all settings of configuration use: ipconfig/renew

Step 5: Restart your computer after completing all the steps

Solution – 3 – Change DNS server

You Have a choice of changing your DNS server by yourself. You can do this if clearing of DNS cache will not work and still show an error then you change your DNS server to Google DNS or OpenDNS. There are some steps mentioned below for doing the same:

Step 1: Open the control panel in your computer

Step 2: Click on Network and sharing center

Step 3: Choose the option Change adapter settings

Step 4: Now various internet connection name appears. Right-click on the correct choice of internet connection which you are using currently.

Step 5: Click on the properties

Step 6: General settings tab open up, choose to Use the following DNS server addresses option and put the IP address of Google Public DNS from 8.8.8.8 to 8.8.4.4

Step 7: Click Ok after completing

Solution – 4 – Resetting of Google Chrome Flags

DNS_PROBE_FINISHED_NXDOMAIN error can also be fixed by reset all the settings of the google chrome. This can be done by typing chrome://flags in your address bar of the google chrome. This will connect your window to all the experimental settings of Google Chrome and now you can click on the Reset option. After that shut down and restart your computer.

Solution – 5 – Antivirus
