[BUG] Unable to run on IDX

[luc1d-ed]

I wanted to run the project on the cloud and avoid installing docker on my PC. I have followed the README and configured everything correctly on the example config file. However I can't get it to run, the database does not recognize the user (Screenshot below). It says:

server-1 | [info] [DbLoop] starting for 0 users

Also the website displays that it is unable to contact to the server, which for context also did when I ran locally and I safely ignored because it still used to work, but that is not the case here.

Expected behavior

The website should be able to communicate with the server and display properly.
