Randomly i got complain from user that they loss access to the network, and if i check on the fnac i got error below

and from endpoint o got this error

Is the error because the fnac wrong send the server certificate? If i replug the LAN cable then the connection is working back.

Since the issue is intermittent, you may need to check the supplicant configuration and the certificates selected on the endpoint. There may be multiple certificates available and the supplicant could be selecting another one. Another possible cause could be network connectivity issues, such as packet loss or MTU related problems.

The RADIUS service logs will provide additional details and can be temporarily enabled if the issue can be easily reproduced.
