Mullvad prevents Windows network connectivity for several minutes out of hibernation

[amoldeshpande]

Is it a bug?

• [X] I know this is an issue with the app, and contacting Mullvad support is not relevant.

I have checked if others have reported this already

• [X] I have checked the issue tracker to see if others have reported similar issues.

Current Behavior

I am on Windows 11 and have set my laptop to hibernate instead of sleep. Effectively every time the laptop resumes from hibernation, I have no network connectivity for several minutes if Mullvad was connected when the laptop hibernated.

I am not exaggerating about minutes. It can take almost 5 minutes.

The usual WiFi network icon is unavailabe in the pop-up when I click on the offline icon (globe) on the taskbar. I usually then enable airplane mode, but that does nothing for several minutes until it finally takes effect. At that point I can now disable airplane mode and everything is back to normal.

I can 100% avoid this problem if I disconnect Mullvad before my laptop hibernates.

I reported this to support and was told the next beta version of the client should have the fix. I see nothing in the Changelog that indicates such a fix for the 4/15 drop, so I decided to file an issue here.

Expected Behavior

Windows should resume from hibernation correctly

Steps to Reproduce

1. Connect Mullvad VPN
2. Hibernate the computer and leave it alone for several minutes (just to be sure)
3. Turn the computer on again and observe the tomfoolery.

I have the same issue, but sleep is enough. So windows 11 and couple of minutes of sleep - when you wake laptop it strangley does not allow wifi to connect (because of this I lost a day troublesooting wifi adapter (mediatek) instead). If I uninstall mullvad, everything works fine. I use mullvad daily on other devices with windows 10 (intel adapter) and android without any issue.
