Tyler Hobbs commented on CASSANDRA-12241:
-----------------------------------------
It looks like {{rpc_address}} is set to the public IP, so connecting to
127.0.0.1 (your first example) won't work. Regarding the second connection
attempt, I'm not sure why you're getting that error. Do you have a firewall or
iptables rules that could be causing problems?
