Cannot connect to any download client

Sonarr version (exact version):
Mono version (if Sonarr is not running on Windows):
OS: MacOS Mojave 10.14.6
Debug logs:

Description of issue: No matter which download client I try, it will not connect to Sonarr. I am running Nordvpn (first on tomatoUSB, then I removed and am using the Nord app). All ports are closed. I literally just spent about 4 hours trying to figure out how to get this working and can’t. Yesterday I tried using docker and nothing connected. Today I downloaded Sonar directly in Mac and was able to get the indexing working (with jackett). Can someone please help?
