Getting RabbitMQ authentication failing even with cookie is set

I have recently installed rabbitmq with ErlanOTP on Windows 10 running on lattePanda

I ran rabbitmqctl status and got the following error:

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.5\sbin>rabbitmqctl status
Status of node rabbit@DESKTOP-V6GQ6RF ...
Error: unable to perform an operation on node 'rabbit@DESKTOP-V6GQ6RF'. Please see diagnostics information and suggestions below.

Most common reasons for this are:

  • Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
  • CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
  • Target node is not running

In addition to the diagnostics info below:

attempted to contact: ['rabbit@DESKTOP-V6GQ6RF']

rabbit@DESKTOP-V6GQ6RF:

  • connected to epmd (port 4369) on DESKTOP-V6GQ6RF
  • epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic
  • TCP connection succeeded but Erlang distribution failed
  • Authentication failed (rejected by the remote node), please check the Erlang cookie

Current node details:

  • node name: 'rabbitmqcli2@DESKTOP-V6GQ6RF'
  • effective user's home directory: C:\Users\LattePanda
  • Erlang cookie hash: 8Kq9f/AaeixMvahU4G2v8A==

How can I get RabbitMQ up and running?

While trouble-shooting I discovered this thread https://groups.google.com/forum/#!topic/rabbitmq-users/a6sqrAUX_Fg

and set the environment variable to Erlang Cookie I found in %HOMEDRIVE%%HOMEPATH%\.erlang.cookie but it still doesn't seem to work.

The RabbitMQ team monitors the rabbitmq-users mailing list and only sometimes answers questions on StackOverflow.

It is important to copy the cookie from the correct location. This document explains where it is located based on Erlang version and Windows version. You don't mention which Erlang version you are using, but I suspect you will want to copy the C:\WINDOWS\system32\config\systemprofile\.erlang.cookie file to %HOMEDRIVE%%HOMEPATH%\.erlang.cookie. You should not have to set any environment variables so if you have, I recommend removing them and restarting your server.
