System.ObjectDisposedException: Cannot access a disposed object

Help & Support
1

Sonarr version (exact version): 2.0.0.4146
Mono version (if Sonarr is not running on Windows): Stable 4.2.3.4/832de4b
OS: Debian 8 (3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2 (2016-04-08) x86_64 GNU/Linux)

I am getting an error using deluge. Sonaar had previously been working fine however Sonaar stopped adding new files.

Doing a bit of investigation I noticed that it was connecting to the indexers but was not able to connect to deluge anymore. When i test the connection to deluge the from the webui it gives me a “System.ObjectDisposedException: Cannot access a disposed object” error.

I upgraded sonaar to the latest version and restarted however i still get the error. Nothing else has changed on the box in the last 2 weeks. It was working fine last week but stopped sometime after last Thursday (05/05).

Below is what happens when I run it in debug mode, the error comes up straight away. Is anyone able to help?

Solved with a complete reinstall of the nzbdrone and mono.

Removed all the config files from ~/.config/NzbDrone and then used “apt-get purge nzbdrone” and “apt-get purge mono” then “apt-get autoremove” to clear the system. Reinstalled everything then it reconnected.

It was a bit of a sledge hammer approach but it fixed it. Will report back if the issue comes back.
