VPN connection problem after Windows 11 Pro 24H2 update

Hi everyone. Yesterday I installed Windows 11 LTSC 2024 on my laptop and found that my Avast VPN is not working. I tried all kinds of resetting network settings but it didn't help.

I installed in a virtual machine from the official ISO images the Windows 11 24h2 Pro and there Avast VPN didn't work either. After that I installed Windows 11 23h2 Pro and there no problem at all, VPN connects without any problem.

It seems that the latest version of Windows does have some compatibility issue of unknown nature.

Thank you Nick.

Please remain on 23H2 in the meantime - a new update would be available tomorrow, hopefully it might have the fix.

I found a solution :)

Please edit your WireGuard profile as follows:

Remove the IP addresses from the section and leave only this:

AllowedIPs = 0.0.0.0/0

Do not change the remaining settings or keys.

It should work.

Let me know once you've tested it and if it works.

Good luck! :)

Hi Sumit and thanks so much for your answer.

I already tried to reinstall the VPN program.

Some colleagues of mine have installed the same update on same hardware and OS and the VPN works correctly, so I wouldn't think it's a VPN certification problem.

I also sent a feedback on the hub and it should have some diagnostic data attached with it, I don't know if you can check it. Here's the link:

Maybe there's some further detail useful to find out the problem.

Waiting for your answer.

Thanks again.

Nick

j'ai aussi fait cela :

gpedit.msc > Configuration de l’ordinateur > Paramètres Windows > Paramètres de sécurité > Stratégies locales > Options de sécurité.
Client réseau Microsoft : communications signées numériquement (toujours)" > Sélectionnez "Désactivé" et cliquez sur "OK".

Mon problème est résolu depuis ;-)
