It also looks like you changed your topology by altering rack from r1 to RAC1. Shouldn't effect this issue but something to get consistent.

I've actually changed the ip address quite a bit (gossip complains on startup and happily picks up the new address),  I think this maybe easier such as..can those ip addresses route to one another ?

As in can the first node with 192.168.xx.xx hit the node with 10.179.xx.xx on that interface?

Cassandra uses the IP address for more or less everything. It's possible to change it through some hackery however probably not a great idea. The nodes system tables will still reference the old IP which is likely your problem here.

To give a complete picture, my node has actually two network interfaces: eth0 for 192.168.xx.xx and eth1 for 10.179.xx.xx

I am trying to change the IP of a live node (I am not replacing a dead one).

So I stop the service on my node (not a seed node), I change the IP from 192.168.xx.xx to 10.179.xx.xx, and modify "listen_address" and "rpc_address" in the cassandra.yaml, while I also set auto_bootstrap: false. Then I restart but it fails to see the rest of the cluster:

Am I doing anything wrong? Thanks in advance

Kind regards,
