Thanks for the responses guys, much appreciated!
@OliverV I ran this install method from here with a Nextcloudpi image: https://raspberrytips.com/install-nextcloud-raspberry-pi/
a2dismod ssl = I ran this and it worked
a2dismod default-ssl = I ran this and got âERROR: Module default-ssl does not exist!â
I should also note that I am running Pihole on port 8888 and this still loads fine. Itâs almost like I messed up port 80 by installing a second certificate? I didnât realize snakeoil was enabled by default until after I ran the commands in my first post. Thing is, it never showed my local IP being secure in the browser URL, it always had it crossed out but the NCP interface would still load. I just assumed no local cert was installed and running.
Basically I was trying to get a local SSL cert running so I could use âNextcloud Yagaâ phone app (it requires SSL) to view my photos from my NCP server.
Anyway, I ran âsudo ncp-reportâ and have attached the relevant system info and HTTP log as the nextcloud admin interface still isnât loading. Thanks again for the help a total newb at all this! Just switched to Linux on my desktop too
