I get an error message “Warning: Unknown Error (0)” and authentication fails.

“Warning: Unknown Error (0)” error message and authentication failure

If you receive the error message “Warning: Unknown Error (0)” and authentication fails, it is most likely related to a problem connecting to the authentication server. This issue can occur if the connection to the authentication server is blocked or interrupted.

Please try the following steps:

1. Check your internet connection
   Make sure your computer is connected to the internet.
2. Check your security software or firewall settings
   Your security software or firewall may be blocking the connection to the authentication server. Please contact your system administrator and ensure that access to the authentication server is allowed.
3. Check if your PC name has changed
   The authentication error may occur if your PC name has been changed since the last successful authentication. Restoring your PC name to its previous value should resolve the issue. If you are unable to restore the original name, please contact our support team for assistance.

If the problem persists after performing the steps above, please contact our support team for further help.
