Description of issue:
hi guys, first time poster. I’ve had Sonarr about 2 months and it’s been great, thanks devs. This error started a few days ago “unable to connect to sabnzbd” Both are on the same pc running Win10
Things I’ve done:
restarted Sonarr and Sab
turned off firewall
removed client from Sonarr and tried to add again
updated to Sonarr 3.0
The only change to the pc was windows updated 2 days before I discovered the problem. I’d like to see if there’s a simple fix before I roll back Windows update.
