Problem: 

nhJoinCluster command to add a CA eHealth system to a cluster gets Timeout

Environment:??

Any Operating systems and any CA eHealth version

Cause:

CA eHealth systems cannot resolve the hostnames 

Resolution: 

Distributed eHealth uses the hostnames for cluster member communication. If a CA eHealth system cannot resolve the hostname to an IP address, or if the hostname resolves to the wrong IP address, you will receive timeout errors. 

To avoid these errors, you can either define the hostnames in the hosts file on your CA eHealth systems (as described in the next section) or troubleshoot the Hosts configuration on your Domain Name Service (DNS) servers. 

You may have changed the IP addresses assigned to your systems and thus the hostname table is out-of-date.
