[Bhardwajp]

Hi All,

We are facing replication issue in our environment we have 8 nodes in our deployment 2 Admin 2 Monitoring and 2 PSN and running dot1x , BYOD and posture services.

On primary node we are getting Replication issue for all other nodes and when we are trying to resync its giving error node not reachable i have check the reachablity and it looks and im able to ping the nodes from IP as well as from Domain name.

Im not sure if Certificate can create an problem can someone please help how i can confirm what is causing this issue ... where is can see logsI 

Thanks in Advance

Hi @Bhardwajp 

Yes, certificates can cause a problem. Have you recently replaced a certificate on one or more of the nodes, ensure the PAN trusts the certificates in use by the other nodes.
