Hi All,
this has me puzzled for quite a while now.
I've been trying to add a 3rd node to our 2-node setup to avoid split brain situation but for the life of me I cannot get the 3rd node inside the cluster.
On a network level a telnet test to port 9300 works.
Everything running in VMware, running on same vlan, so only iptables to think about and that's all done.
Here's the error:

Any help would be appreciated. I've seen similar topics on the interwebs but none provide more insight into the problem...
Kind Regards
