I only bring it up because you explicitly said you have no idea why it doesn't work.

Take things at a comfortable pace; there's no sense overwhelming yourself. Then you just forget what you've done and end up lost in your own maze.

I started with Plex myself, almost 10 years ago. Moved to Emby, where I learned about buying a domain, setting up ssl through a reverse proxy, and just continued to explore from there. Today I run ~26 containers/projects across three systems and I'm always keeping my eye out for interesting new things.

Best of luck with your journey m8.
