[Resolved] Wireguard VPN stopped working?

[PeterAndersson]

Hi thanks for a great product, it has been rockstable!
But all of a sudden my wireguard VPN connection between my phone and OPNsense stopped working, but I'm at a loss where the issue is located.

I'm running the latest version of OPNsense and I'm using an Android phone running Android 14, and in the app I can see that it sends data but none is received.

The logs for the wireguard VPN Server shows nothing that seems like it could cause it.

So the issue could be in
* OPNsense
* Android
* The wireguard app
* My phone plan provider

I'm 100% sure that my phone can reach my router as I can reach my webserver that listens on post 443.

If I do a package capture on the udp port I run my wireguard server nothing is detected.
But if I do a package capture on my phones ip, I can see a few TCP packages being received.

How would I go about debugging the issue?

After changing the IP Address in the client application and then changing it back to the original value it works again.

I have no idea why.
