Sonarr can no longer connect to SABnzb

[njackland]

Sonarr version (exact version): 3.0.3.679
Mono version (if Sonarr is not running on Windows): 6.4.0.198
OS: Mac OS Mojave 10.14.6
Debug logs: https://drive.google.com/open?id=1YGIXtDTm6L1YEuK6lzB0Vwxgf-6NJCxP
Description of issue: I have had Sonarr and SABnzb working well for over a year, but all of a sudden the two can no longer connect. I haven’t changed any settings but did update Sonarr to the new UI version recently. After the initial Sonarr update it was working.

SABnzb will still manually download, but Sonarr will not integrate at all.

I would really appreciate some help!

Thanks in advance!

Either fix the cert or disable certificate validation for local connections (new in v3), it’s in General settings.

Thank you! This fixed it right away!

If you close SABnzb, delete both these files (see below) and restart SABnzb, that will cure the problem as they will be re-created upon startup

Windows:
%localappdata%/sabnzbd/admin/server.cert
%localappdata%/sabnzbd/admin/server.key
Linux:
~/.sabnzbd/admin/server.cert
~/.sabnzbd/admin/server.key

Cheers
