Power Panel interface of a container is not accessible while the container is being backed up ("An invalid username or password. Please try again" error message is received on the login attempt.


The Backup operation for a container requires it to be locked from any other operations (vzctl start,stop,exec) until the backup is completed. Since the container is locked, Power Panel will not work until the end of the backup operation.

The services inside the container remain operable during the backup.


Wait for the backup operation to be finished.
