Anyone know how to fix error 'Supplicant stopped responding to ISE'? I try to increase 802.1x timer but not helping.
When we use EAP-TTLS is mandatory that ISE certificate should be apply in the endpoint?

5411 Supplicant stopped responding to ISE |
| Failure Reason |
12981 Supplicant stopped responding to ISE during EAP-TTLS tunnel establishment |
| Resolution |
Verify that supplicant is configured properly to conduct a full EAP conversation with ISE. Verify that NAS is configured properly to transfer EAP messages to/from supplicant. Verify that supplicant or NAS does not have a short timeout for EAP conversation. Check the network that connects the Network Access Server to ISE. |
