Authentication failed (rejected by the remote node), please check the Erlang cookie
Solution 1
The docs says you should copy the other way...
If the Windows service is used, the cookie should be copied from C:\Windows\system32\config\systemprofile\.erlang.cookie to the expected location for users running commands like rabbitmqctl.bat.
See http://www.rabbitmq.com/cli.html
Solution 2
In case, like me, you need this stuff really spelling out:
- In FileExplorer navigate to your user directory. (Paste
%userprofile%
in the address bar.) - If you already have the file
.erlang.cookie
in there, delete it. If not, just go to next step. - In a second FileExplorer, navigate to
C:\Windows\System32\config\systemprofile
. - Find the file
.erlang.cookie
and copy it to your user directory.
Now your rabbitmqctl
should be able to authenticate.

Answer by Robino helped me nail the issue.
I had two different .erlang.cookie
file -
one in admin users/admin
and
another in users/myprofile
I copied the one in C:\Windows\System32\config\systemprofile
to both the locations users/myprofile
and users/admin
.
Also I copied the same cookie file to my Rabbit installation %Rabbit_Home%\sbin
where I am running my rabbitmqctl.bat
.

After having this exact issue myself, the problem was solved by running the service under my account. Try this if you are still facing the issue and have reinstalled.
Solution 5
Check the version of erlang you installed. rabbitmq v3.7.0 match with v20.1.x of erlang. supported version of Erlang

I installed erlang and rabbitmq in the way mentioned in the official documentation. But then, when I do this
C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.0\sbin>rabbitmqctl add_user XXXXXX YYYYYYY
it gives me the following error...
Error: unable to perform an operation on node 'rabbit@C001741998'. 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:
- See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
- Consult server logs on node rabbit@C001741998
DIAGNOSTICS
attempted to contact: [rabbit@C001741998]
rabbit@C001741998:
connected to epmd (port 4369) on C001741998
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: rabbitmqcli49@C001741998
effective user's home directory: C:\Users\XYZ
Erlang cookie hash: QJlwBuAgrn8gN00mjqQYOw==
I copied the erlang cookie from my user home folder to C:\Windows folder. So, they both have the same cookie. Still it keeps throwing me the error. Not sure how it should be fixed. Any help??
UPDATE
I figured out that the best way to run rabbitmq is from docker container. In that way, you do not need to bother about any cookie or dependencies, also you get rabbitmq up and running in few minutes. Hope it helps someone!
