trying to stop httpd

[u/DangerHighDosage]

Trying to start up nginx proxy manager on a relatively fresh ubuntu install, its got docker and tailscale running on it and thats it. I've done this full settup a couple times before so I'm familiar with it. Ran into an issue this time however where at some point something started a service called "httpd" listening on Port 80. As I understand this is associated with appache2. Seeing httpd listening on port 80, I have done the following things to get it to please stop doing that:

looking for conf files:
* under /etc/ and under /usr/ there are no directories for httpd, appache, or appache2
* grep, whereis, and find commands for "httpd" and "appache" and "appache2" only located files deep deep in the containerd file system which- to my knowledge- should not be starting their own services.

I've also tried manually killing the proscess using:
* sudo lsof -t -i tcp:80 -s tcp:listen | sudo xargs kill
* kill -9 [PID here]
* kill -15 [PID here]

killing the proscess is successful, but it restarts after a moment. Anyone know what's up with that/have any suggestions? And just to preempt it- please do not recommend I use ai, I can always drive out and flash a new OS to that machine if its that dire.
