Can't open RabbitMq after installation on Windows

Question

I was receiving this error when accessing http://localhost:15672 with user guest and password guest (default credentials)

undefined: There is no template at js/tmpl/login.ejs undefined

So I restarted the rabbitmq service from services.msc then by mistake started also the Radio Management Service. After doing this, http://localhost:15672/ wouldn't even open. It says:

localhost refused to connect. Search Google for localhost 15672 ERR_CONNECTION_REFUSED

So I stopped "Radio Management Service", tried to open rabbitmq again, same thing: ERR_CONNECTION_REFUSED.

So I uninstalled both Rabbit MQ Server and erlang.

Then downloaded them from the official site and reinstalled them, first the "Erlang for Windows installer 64-bit" and then the "rabbitmq-server-3.6.12.exe".

However, I still get ERR_CONNECTION_REFUSED (when trying to access http://localhost:15672/).

I didn't know what exactly I should allow through firewall so I added all exe files found in C:\Program Files\erl9.0\bin

Restarted RabbitMq from services.msc. Still ERR_CONNECTION_REFUSED.

Am I missing any plugins or something?

Next, I ran the command rabbitmq-plugins enable rabbitmq_management from the RabbitMQ Command Prompt found in C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.12\sbin, however I got:

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.12\sbin>rabbitmq-plugins enable rabbitmq_management Plugin configuration unchanged.

Applying plugin configuration to rabbit@MYPCNAME... failed. * Could not contact node rabbit@MYPCNAME. Changes will take effect at broker restart. * Options: --online - fail if broker cannot be contacted. --offline - do not try to contact broker.

I am at a loss. What else should I try?

*** Later edit:

I also removed and readded the rabbitmq service in case that was related to the core issue at hand:

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.12\sbin>rabbitmq-service remove C:\Program Files\erl9.0\erts-9.0\bin\erlsrv: Service RabbitMQ removed from system.

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.12\sbin>rabbitmq-service install C:\Program Files\erl9.0\erts-9.0\bin\erlsrv: Service RabbitMQ added to system.

and then reattempted to:

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.12\sbin>rabbitmq-plugins enable rabbitmq_management

...with the same error as above. (could not contact node etc)

So, the service you started seems to be related to Window's airplane mode more information here. This might explain the connection problems. Were you able to stop it in the meantime? — José Belo
Radio Management Service is stopped and on manual after PC restart. Shouldn't this be the default? Thank you José. — Sami
According to this, yes it should. Can you access RabbitMQ now? — José Belo
Well, this post here has lots of suggestions besides the one you tried. Might it be that you have multiple files .erlang.cookie in your computer? — José Belo
Thank you, it worked. I copied C:\Windows\.erlang.cookie over C:\Users\yourusername\.erlang.cookie ; then I deleted all folders in c:\Users\xxx\AppData\Roaming\RabbitMQ\db\ (xxx is your username) ; what finally did it was to Run RabbitMQ sbin command prompt as administrator.and type the command "rabbitmq-server restart". Strangely enough, I get this problem on a recurrent basis and applying these steps does the trick. Thanks so much. The solutions were found on the thread you indicated. — Sami

You might need to enable rabbit management pluggin. By default it's not enabled. Run the following command: rabbitmq-plugins enable rabbitmq_management

Then restart your service. Should work.
