Yesterday I've lost a few hours with this same problem and it was in a fresh install, so the problem was that the erlang cookie from my user and root user was different than the one from rabbitmq user.

• Find out the HOME for the user rabbitmq:

  # cat /etc/passwd | grep rabbitmq
  

• Check if the cookies differs from each other:

  # vimdiff /var/lib/rabbitmq/.erlang.cookie ~/.erlang.cookie
  

• If they are different, copy the cookie from rabbitmq for the user that you want to have access to the server:

  # cp /var/lib/rabbitmq/.erlang.cookie ~/.erlang.cookie

• rabbitmqctl status says "TCP connection succeeded but Erlang distribution failed"
