Strange WireGuard Site-to-Site Behaviour

[micharambou]

As suspected - the test confirms that the issue must be somehow service related, since a raw TCP Connection is established successfully.

Would you clarify, which particular service is running on the server?

I'm using Radarr (https://radarr.video/).

Unfortunately still having issues. Any ideas as to how to add an exception to the firewall?

FYI I've had this exact same setup with PFSense and OpenVPN before I switched over to OPNSense & WireGuard, and every service worked previously.

Any ideas relating to firewall rules?

Not sure why it's only this service that has a problem.
