Windows clustering - unable to connect to epmd (port 4369) on rabbit@X nxdomain (non-existing domain

[Manish Kumar]

I have two windows machine and both are running RabbitMQ as a service. Both machine can access to each other ( I used telnet to check if both can access port 4369) but when I am trying to cluster them using below command  getting error "unable to connect to epmd (port 4369) on rabbit@X nxdomain (non-existing domain"

rabbitmqctl join_cluster rabbitmq@rabbit@XXXX

I checked and make sure that erlang cookies are same on both machine. I am stuck now, please help. Thanks!

“nxdomain” means “domain does not resolve”. The node on which you invoke the CLI command has to be able to resolve and contact the host.

I suspect that rabbit@rabbitmq@HOST is a typo and you really want rabbit@HOST which is the default node name (which can be overridden, though).

rabbit@rabbitmq@HOST :- Yes, this was a type.

I tried telnet and able to connect to server over port 4369, could you please suggest how to resolve it.
