HI

 

I have able to found a solution for this issue.

 

This Failed to contact policy server error got because of the DNS error. If temporal agent could not able to resolve FQDN as defined for G0 on ISE primary server this error occurred.

 

FQDN (“hostname” and “ip domain-name”) of the ISE admin server itself must be added as a DNS entry.

Great! Yes all your ISE Nodes should be resolvable via DNS forward and reverse lookups for proper functionality
