OK that’s fair, so you manually created a docker network named an error code and then assigned a 192 subnet to it.
As a quick note, you blanked out the ipv6 in your subnet section, but left it showing in the containers, you may want to do a quick edit and obfuscate that!
You mention radarr can ping jackett and deluge, did you actually test that? This is a good test to establish internal connectivity. If that works, i would assume this implies a failure to nat the traffic out onto your LAN (and thus to your WAN)
In this case, the errors you show in your radarr log seem to imply a lack of network connectivity. I would blow the config directory away, stop and remove the container, and recreate it.
