Getting Socket connect failed after enabled resilient network.
Telnet on port 13724 both server to client and client to server is fine. But bptestbpcd command failed with Socket connect failed. If disable the resilient network, connectivity is fine.
Is a another application than Netbackup using port 13724 ?
command "netstat -n" on Windows should be able to answer that qustion. On Linux/Unix command is the same but the argument will be diffrent.
This also appears to be virtually the same as a post you opened in 2014:
In that case, it was dsiabling Resilient Network that was the fix. Seems you have the reverse issue now :)
Normally, I will enable resilient network if backup on that client fails consistently with error 40 or 41, or other network-related error code.
If you don't get those, there is no need to enable.
If you really need to enable it and getting error, as mentioned earlier enable & check nbrntd logs.
