Windows 11 gives warning message when connecting to WPA2 Enterprise network

Since we started installing Windows 11 on several laptops in our department we started to notice this message:
![144615-image.png

First we thought our NPS Server and Certificate are too old (Server was 2012 R2, certificate was SHA1) but after upgrading both (Server is now 2019 and Certificate is SHA256) we are still getting this message.

As some of our devices are still using Windows 10 we tested with those and they are connecting flawlessly.
Anybody have a idea what we may be doing wrong or is this now the "normal" behaviour with Windows 11?

    Hello @Limitless Technology ,

    thanks for pointing in the right direction.
    In fact our GPO that was giving our clients the WIFI profile was not correctly configured, we set the checkmark that the client should validate the certificate but not which Server and also we didn't check the box which Certificate is our Root, after setting those two options it is now finally working again.

    Thank you very much for your help, it is much appreciated.
