ConnectionRefusedError, Error 10061 on demo project

Hello,

I am using a Windows 10 PC from my workplace and invested some hours to get all install scripts etc. working. I finally managed to get everything installed and can run the Django server.

I can connect to the server via localhost:8000 and see the main page. Though, the connection does not work with http://127.0.0.1:8000. It seems like Django is running without problems, but when I go to any example page, the server console always outputs a ConnectionRefusedError. When I go to the page of example 2, it even shows error 10061 (ConnectionError at _demo-two.pdf). After any of these errors occurs, the server does not work anymore and needs to be restarted.

It seems like the ports are blocked or something similar. I found related issues, but they did not state this exact problem. Inputting this into the requirements.txt and dev_requirements.txt did also not help: https://github.com/GibbsConsulting/django-plotly-dash/issues/126#issuecomment-472019350

Next, I tried to resolve all version conflicts and downgrade several versions of different packages, but then, the server did not even start anymore.

I tried out the server without any network connection, inside the company’s internal and external network.

One thing that I can not change is that there is McAfee Endpoint Security installed. It cannot be closed or deactivated (or I just did not find a way to do that with my Admin privileges).

This are the batch files i wrote for installation and starting the server:

installer.bat

That connection error is because you don’t have Redis running.

See this part of the documentation for the installation instructions.

@kartom In order to determine if there is a problem, rather than just incorrect configuration, it would be helpful if you could supply some information about the installation and configuration steps that you have taken. Without that, it is not possible to comment further.

For example, the settings here and also here impact the serving of these assets.
