Hi All,

In my environment we have added Meraki as the radius client in the NPS server, then NPS extension is installed with Azure MFA

Now the problem is, when we connect the Meraki WIFI through mobile, it is prompting for the Username and Password, After that the MFA challenge is also accepted in mobile phone, but we were keep receiving the MFA notification in Microsoft authenticator APP.

We are using Microsoft protected EAP (PEAP) in the network policy. I have add the MTU in both Lan card of the NPS sever and network policy with the lower value i.e 1344, but still we were keep receiving the MFA notification in Microsoft authenticator APP.

Does anyone faced the similar type of issue, Let me know if i am missing anything ?

Does the MTU value in the NPS server and Meraki device need to be lowered ?
