Hello! A few questions:

  1. Do you have a multi peer config or just one peer?
  2. Does this only occur with the restart on ping fail feature active or have you seen this behavior without that feature?

Thank's for your reply.

  1. Just one peer.
  2. It does occur with the "restart on ping fail feature" disabled. I've had this issue on older versions also.

After the issue occured again I was able to generate some logs (adb logcat):

This goes on and on.

I will try to generate some WG Tunnel logs from within the app.

kafisc1 commented 4 months ago

I can't create logs from within the app because the app crashes before I can generate the logs.

But I can reproduce the issue following way:

Set "Auto-tunneling" to Pause and connect to wireguard profile manually. Wait till the conenction is established.

Click on the connection button 2 times per second for about 4 seconds. After 4-6 clicks on the connection button the issue occurs. In the attached video the issue occurs after 10 seconds going onward. Crash WG Tunnel
