While accessing Tools & Settings > IP Address Banning (Fail2Ban), the following error is shown:

 Internal error: f2bmng failed: ERROR:f2bmng:Timeout of 10 seconds has been reached. Lock 'service.fail2ban' is already owned by another process with pid <unknown>


 502 Bad Gateway


Incorrect/Incomplete installation of Fail2ban packages. When Plesk tries to get the service status for fail2ban, the process hangs and return a timeout error.


Reinstall the fail2ban packages using autoinstaller.

If it is required, remove all found parts of fail2ban from /etc/ and other found places.
