What’s 8080? Nginx?
This:
Anything can use it, but I think by convention it's used for http on a non-privileged port.
It's the default port most applications use when they run an integrated web server.
Not really, they'd clash all the time. 8080 is the default port for a non-privileged webserver, that is, web server, something you put your own stuff on, not applications/daemons that happen to have a web interface. E.g. ComfyUI uses 8188 for its web interface, deluge 8112, neither will serve your index.html.
Well they all have their own web service, that's how they can deliver the interface. Of course there are a lot of applications that know they will run aside with others because they complement each other and will set a default port that won't interfere with them, but it can still happen and that's why you can change the port. 8080 (and 8008) are just the official alternative ports for HTTP traffic and thus still often set as default in the configuration of many applications.
Default secondary port for Apache tomcat HTTP web servers which are pretty common
The reserve 80 port.
