So your native nginx process covers ports 80 and 443. which ports does your NPM use? Are you trying to use the same ports? Because that’ll most likely clash.

Joomla worked well for me.

The ones from the applications which should do the proxying and serving.

BTW: you’re using both Nginx Proxy Manager and Nginx in parallel? Native installations, docker, something else?

How are they configured?

Post more logs/configs

Good question. I haven’t really tried that yet, most of my media plays natively, sometimes the audio needs to be transcoded, but that’s done by the CPU.

I moved from a 2700x to a 5700g. iGPU and faster than the old one, but compatible with my old mainboard.

My advice is to put all the server-y stuff on a server and use other machines for the rest. Far easier to keep that stuff separated, although you need an additional machine.

Feels like blaming others for not paying attention.

Well? What did you do?
