I am trying to install Cassandra from LCM to new DC. But getting below error altough we have added private key.

I have also tried with ssh credentials but it also did not work out.

LCM version: OpsCenter 6.1.6 
OS: centos 7

The problem is reported in your log: Failed to establish a new connection: [Errno 113] No route to host . I think that you need to check that destination node is running, and also firewall on both OpsCenter server & destination host.
