Subject: C* 3 node issue -Urgent

Hi Everyone.

I  need the communities help here.

I have attempted this morning to turn on JMX authentication for Nodetool. I've gone into the file and updated the following:


Then I restarted each node, I have 3 of them  in a single DC, Single Rack.
115.63 (seed)
115.65 (seed)

Nodetool status shows this


In the Yaml I have Authentication turned ON.
Cassandra has been working flawlessly up until the moment I restarted the nodes.

as it stands right now..

115.63 is up, but I cannot connect to CQLSH
I get the following error

When I check the logs I on 115.64 and 115.65 I can see this
