RPCN Login Error: User Already Logged In

Hi. I've got a problem that seems to exist for some people, however it doesn't seem to be resolving by itself and I wonder if there's anything I can do to fix it? I tried testing out RPCN about more than 6 hours ago and everything worked fine, however I switched my internet connection and now I can't log back in. I assumed the server would drop my connection that no longer exists after a few minutes, but it's been more than 6 hours and I just tried logging in again and it still gives me the same error. I've attached the log file and the screenshot of the error. This makes me unable to play online.
