Connection to backend lost

[Duzii]

Hi

I have never had any issues with Sonarr until now.

I can start Sonarr but when the RSS sync and library update starts Sonarr hangs and the "connection to backend lost" message appears. I think it has to do with the new Mono version I updated to in the app central?

The last entry in the Debug log below:

Code: Select all

16-11-26 11:14:55.4|Debug|GlobalExceptionHandlers|Minor Fail: The type initializer for 'System.Drawing.GDIPlus' threw an exception.

After I close down Sonarr and start it again the GUI is not loading. I can restart Sonarr using Putty and below command but it still hangs again when the RSS sync and library update starts

Code: Select all

rm /usr/local/AppCentral/sonarr/config/nzbdrone.pid
/usr/local/AppCentral/sonarr/CONTROL/start-stop.sh restart

I found others with similar issues and their solution was to downgrade Mono. How do I do that?

I managed to update Sonarr to the newest version before it hanged and now it seems to be working fine again.
