[BUG] - Stuck on resolving DNS on while booting private space

[Eskuero]

Describe the bug
I have an WG Tunnel installation in a GrapheneOS private space. The difference with other stock private space is that this has enabled "End session inmediately on lock" which translates to the apps installed inside being killed when the private space is locked rather than just latent in the background.

When this function is disabled everytime I unlock the private space WGTunnel reconnects without issues.

But when this is enabled the tunnels seems to get stuck on "Resolving DNS" for two minutes until it timesout and retries again connecting correctly. If I interrupt it and start it again it works immediately without having to wait. This happens regardless of using the Peer resolver in "System" or "Plain DNS (port 53)" mode. What I noticed is that in "DNS settings" it would say "No system DNS have been detected" until it eventually figures it out.

My guess is that WGTunnel tries to start so fast under the assumption that the system network interface is always up but in this particular instance it may not be yet so it gets stuck for a while.

Smartphone (please complete the following information):

• Device: Pixel 9 Pro
• Android Version: Android 17
• App Version 5.3.1
• App mode: VPN

Hello!

Thanks for the report. I'll take a look.

Hey,

Follow up question on this one:

Does manually restarting work instantly even if done within the first 10 to 20 seconds of the stall, or is it only instant when done after you've waiting a while.

I'm leaning toward this being a private space GrapheneOS quirk not reporting the active network for a while.

It's done instantly after opening the private space, just go to WGTunnel and see it stuck on "Resolving DNS", toggle off and back on which results on the tunnel working again.

It's true tho, that in very few occasions the tunnel might start up correctly without help and also a few times the toggle off/on might not work the very first time and I have to do it again.
