I followed this guide https://www.rabbitmq.com/install-debian.html and installed rabbitmq-server. However, it won't start with an error message:

I tried to do this installation on a clear instance of Ubuntu and got the same error. I googled the error message and it seems I have some problem with network settings - I guess I should change some settings from their default state.
Any idea what needed to be changed? Or with which setting I should take my first try?
P.S. I'm completely novice in Unix. For me, it's just a cloud environment where I run my Python scripts.
