VCS ERROR V-16-10-4
Could not connect to a live system in the cluster :14141
Closing all windows
 

This is frequently fixed by proper DNS.  Both forward and reverse DNS need to work.

Also you could have a firewall blocking communication ports.

The best solution is to have DNS function properly.

(example - forward)

# nslookup cluster-1.domain.com
Server:         10.0.0.251
Address:        10.0.0.251#53

Name:                     cluster-1.domain.com

Address:                 10.0.0.21

(example - reverse)

# nslookup 143.127.10.28
Server:         10.0.0.251
Address:        10.0.0.251#53
 

Non-authoritative answer:

21.0.0.10.in-addr.arpa      name = cluster-1.domain.com.

If this is not possible, you can modify your hosts file. 

(note windows does have a hosts file as well) 

Unix - /etc/hosts - typically

Windows - :\\system32\drivers\etc\hosts

The VCS Java client requires Bi-directional traffic on the following ports:

14141/TCP

14150/TCP

These can be tested with the telnet command if it is installed on the machine attempting to connect to the server.

$ telnet cluster-1.domain.com 14141
Trying 10.0.0.21...
Connected to cluster-1.domain.com
