I'm following this fucking tutorial (https://blog.ssdnodes.com/blog/...) and everything goes well, I have docker running, docker compose installed properly, but when I start trying to create the docker-compose.yml and accessing the stupid site using the virtual host domain i set I can't it keep getting "503 Service Temporarily Unavailable" or "502 Bad gateway" what the hell am i doing wrong, I just want to get this working in my VM so i can move it to my damn server and have my own fucking cloud. This damn bullshit is exactly why i went into programming rather than dealing with configuring servers and bullshit like this i know it's outside my level of understanding but I really fucking want my own cloud system but I want it containerized for both isolation and learning purposes.

I have no idea what the hell i'm doing wrong and all the damn articles and links i'm reading aren't helping at all with my level of stupid not allowing me to understand what i'm doing wrong
