Replication cluster problem

Dear Members,

I have a problem with my ElasticSearch cluster in Couchbase XDRC configuration.

I put as IP because my elasticsearch is in the same server as couchbase (3.0.0). Then the system change that by public IP (92.222..) of my server. It is very strange. Do you no why ?

Log show " <<“Could not connect to “92.222..” on port 9091. This could be due to an incorrect host/port combination or a firewall in place between the servers.”>>,"

It’s normal due to my firewall. I would like to put as persitent.

Couchbase log show : Updated remote cluster ELS hostname to “92.222..:9091” because old one (“”) is not part of the cluster anymore
