I have installed couchbase 4.0.0 RC version on two machines on same network. i am facing problems in adding server to cluster. below is error
Prepare join failed. Error connect_timeout happened during REST call post to http:****************:8091/engageCluster2.
Not sure whats the problem. If i install other version it works.
I would verify that both machines can successfully connect to port 8091 on the other machine - perhaps you have a firewall blocking that port?
You can verify connectivity on that port using telnet - e.g. from host1 -> host2:
telnet host2 8091
and see that you get a connection successfully established (and also the check the opposite direction).
Thanks drigby, it was firewall blocking. now its working fine.
