Bad decrypt error on openvpn GUI but not with openvpn connect

[Mr_Livre]

Hello.
I have set a PiVPN (setup that works fine with the android app openvpn connect but on windows 11 openvpn Gui (ver 2.6.0) I have this error :

Code: Select all

Tue Feb  7 10:39:23 2023 Restart pause, 1 second(s)

I tried some differents profiles but the results are the same.
Do I have to inspect the server configuration or it's the client the problem?
Thanks

I found the solution, topic can be close.

Could you share your solution?

My user had to route the port 1194 UDP/TCP to his machine. It's weird because I have set the port to be used to 443.
And on other configurations users don't have to do this route (same ISP same router).
