rabbitmq-server fails to start after hostname has changed for first time

Question

I am using django-celery for my django project. Last day I have changed my computer\'s hostname (I am using Ubuntu 12.04, edited file \'/etc/hostname\'), and after next restart

Answer 1

On Windows, the issue I was facing was due to the McAfee firewall. The exact error was:

epmd error for host "": address (cannot connect to host/port)

It started working as soon as I disabled the firewall
