We have deployed a new site and are having issues with the EAP-TLS. We use the same profiles for each of our locations and there is no difference between this location and others. PEAP authentications are working without issue but EAP-TLS (profile that works at other locations) ISE shows the Supplicant abandoned the session and started a new one. I have a TAC case started but we have not made any progress. Wired EAP-TLS works as well. The setup and WLAN's are the same across all locations, I have a good capture and a bad capture and it appears the difference is the supplicant never provides the certificate for authentication.
Any suggestions would be appreciated.

We were able to resolved this issue by enabling tunnel path-mtu-discovery on the GRE tunnel and "enabling" ip unreachables.
