I've had the Wireguard Android app on my chromebook for awhile and it's seemed to work just fine. Recently I've started using it more though, and I discovered that if I closed the lid of my chromebook for a few minutes or if I let it go to sleep that I can no longer get any of my tunnels to work. Toggling the tunnels and/or wifi does not fix it, nor does force stopping the wireguard app. I have to do a full reboot to get things working correctly again.
I did some debugging and discovered that the wireguard packets were still being sent to and received by the remote server, but there was something incorrect about them because they never appeared on the corresponding wireguard interface on the server. I didn't see anything that stood out in the app debug log either. After some searching I found a reddit post where someone discovered that if they downgraded to version 1.0.20210506 that the issue went away. I didn't try that myself yet because I don't really want to enable dev mode to allow sideloading apps right now. I can enable debug mode for wireguard on one of my servers to get more info if it would be helpful, but have yet to do so. Here's a link to the reddit post: https://www.reddit.com/r/chromeos/comments/q0lbnl/network_troubles_after_version_93_update/ Reuben
