i used to ask my WIFI user connect via RADIUS authority from Microsoft NPS server, but i got the error event below.

while i checked the certificate of PEAP types on NPS i find the error below while i click edit "Microsoft: Protected EAP (PEAP)", is it because the certificate is not correct? how to fix the issue?
