I am trying to setup replication between two clusters that were recently re-initialized. The clusters are both a combination of Gen3 and Gen4 nodes are are running 4.01. Following the documentation I created the application pool and profile on the target cluster, exported the pool/profile list, imported it on the source cluster, and then enabled replication using the 'set cluster replication command'.

But when issuing a "show replication detail" on the target cluster the results are:
"Replication disabled"

And issuing a "show replication detail" on the source cluster the results are:
"Replication paused: yes (authentication failed)"

Any thoughts on where to look to determine why the authentication is not working between the two clusters?
