Celery worker cannot connect to RabbitMQ

[CyberKaizen]

What happened

I followed the exact instructions to setup IntelOwl and got stuck on this part. https://intelowl.readthedocs.io/en/latest/Installation.html#run

When attempting to stand up IntelOwl on a Linux VM hosted by an ESXi server the repeated issue comes up that the celery worker cannot connect to the RabbitMQ docker container.

If I just use VMware Workstation Pro and follow those same instructions, there are zero problems.

Environment

1. OS: Ubunu Server 64-bit
2. IntelOwl version: 4.0.1

What did you expect to happen

For IntelOwl to work on an ESXi host just like it worked on VMware Workstation Pro.

How to reproduce your issue

Follow the instructions for standing up IntelOwl, but do it on an ESXi host.
