WireGuard ProtonVPN connection active, but unable to receive responses

[ctrom]

I have followed the documentation for setting up WireGuard with ProtonVPN. The VPN status indicates that the connection is online, the handshake age is being refreshed regularly, and there is data being sent and received, although the received traffic is about 1/4 of the sent traffic. I am able to ping the address Proton specified (10.2.0.2) but pings to 8.8.8.8 are lost and attempts to curl -v http://neverssl.com result in Recv failure: Connection reset by peer

I have tweaked many settings and spent a few hours going back and forth with Gemini trying to identify what's wrong, but have had no success. I'm hoping for suggestions on what I should try or how I can diagnose where the failure is occurring.

Not sure if this applies, as I do not use ProtonVPN, but have you tried looking at Firewall: Log Files: Live View? It helped when I was setting up WireGuard. Turn on logging here: System: Settings: Logging and Firewall: Settings: Advanced.

Yes, I have enabled logging on all of the firewall rules related to the VPN. When I look at Live View, I see many requests that are passing from local IPs out of the network, but nothing from outside coming in. I've also looked at the VPN logs and the system logs and I haven't seen anything that indicates to me a failure condition.
