- Initially from the first screen it seems that there are not any radius server's defined in the group 'radius' ; that being said and to make things clear and or avoid possible confusing on the switch I would advise to give the group another name then just 'radius' ; such as for instance authserversgroup , then change the running config accordingly.

Thanks for your reply.
actually, the aaa config is being pushed by Cisco DNA center to the switch, so I assume config should be fine.
I did another test and intentionally typed wrong password. I got a rejection from the ISE server:
The error message appears when trying to authenticate with correct credentials. switch loses response with the ISE server for a period of time then everything restored again!

- Returning to the your initial screenshot I see :
%RADIUS-3-NOSERVERS: No radius hosts configured....
I still find this strange ; verify with show run | inc radius

- I can't see any real and or effective definitions of radius servers in there ; check for instance ,
