Synology Cloud Sync error
Today, I saw a red error icon in the taskbar of the Synology app, displaying the statement "Sync Error" and the details "Sync folder does not exist".
Opening the settings clearly indicated that the folder exists. Additionally, the latest changes have been synchronized. So it was the wrong status.
UPDATE: This proposed solution does not work! After stopping and reactivating the package, the error reappears. Obviously, others also run into this issue these days:

This can be fixed directly in the SQLite database:
Login with SSH: <admin-account>@<nas-ip>
Elevate permissions: sudo su
Connect to database: sqlite3 /volume1/@cloudsync/db/config.sqlite
Fix the state: UPDATE session_table SET error = 0 WHERE error = -12;
Quit the SQLite prompt: .quit
Stopping and restarting the Cloud Sync package was not necessary, but it might be a good idea.
