System Information

• Operating System: macOS 10.11 El Capitan
• .net Framework (Windows) or mono (macOS/Linux) Version: 3.12.1

I have the same issue.

Version: 2.0.0.5163
Mono Version: 3.10.0
Operating System: FreeNAS 11.1-U5

[markus101]

You'll need to upgrade mono to fix that error.

[skube]

OK, thanks! Just curious, did this change recently? It was working fairly recently and it just seems like a big jump from 3.10 to 5.12.

For anyone else interested, I downloaded and installed Mono 5.12.0. Then restarted Sonarr. Works again!

[krazydave]

I updated my mono and restarted and it worked also. Except after a few days, it stopped working again, failing with the same error. Restarting Sonarr will get it working again for a few more days, and then the cycle repeats.
Not sure what else to try at this point aside from starting a new jail from scratch which I'm trying to avoid doing.
