3 years ago I do not use Apache, but maybe my experience may help you @LostinSpacetime .
Nginx (a web server like Apache) acts as the main door to many applications running in various containers, i.e., nginx acts as a proxy. Some applications may need some time to be responsive. If nginx does not get a response, nginx may output 502 Bad Gateway.
On my machine it may make up to thirty seconds until relevant applications are responsive.
I am a teacher trying to to setup BBB for our school in Vienna. I followed the instructions including the integration with Apache and after starting all the containers, instead of getting the default site, I get a nginx "Bad Gateway" message when using the domain in a web-browser. Also I get a "error/mod bigbluebuttonbn/view error unable join" when trying to connect the BBB-server via Moodle. The server I'm using is running Plesk.
