PLEASE HELP me - RabbitMQ localhost management failing to launch with port 5672 errors in the log file

[vyankateshss]

Hello All,

I hope you all are doing good!

I have installed RabbitMQ version "rabbitmq-server-3.11.2.exe" and Erlang version "otp_win64_25.1.1.exe" on Windows 10 machine.

I am very new to RabbitMQ and I am unable to launch RabbitMQ management portal. I enabled the RabbitMQ management plugin as well.

Searched the internet with all sorts of suggestions on StackOverflow, Google groups and other forums and all of them failed.

In the log files I find a whole lot of errors like below.

I have diabled McAfee firewall, I have added port 5672 to McAfee firewall, reinstalled the app at least 10 times, opened the port 5672 in windows firewall security, tried on docker images as well but my 3 days efforts failed to start it.

I have attached RabbitMQ and Erlang log files in here, please provide your valuable suggestions.

Great thanks for your kind consideration.

Please ATTACH your full RabbitMQ configuration files any time you report an issue with RabbitMQ.

Here are the two interesting lines in the output above:

cacerts,'...'},{key,'...'},{cert,'...'},
`eacces (permission denied)`

You appear to be trying to use X509 certificates, but RabbitMQ can't read them. Fix this permission error.

Apparently this was actually due to another process using port 5672
