Your ports are not mapped so the host system doesn’t know about them. You only have them exposed, which is for docker communication.

Map your ports and then you’ll be able to access them by host-ip:mapped-port.

Then you can use nginx to proxy to that.

I decided to start blocking the people posting them. It turns out, it was literally one user making it a spam problem. I blocked one or two more on principle and haven’t seen a moth meme since.
