This version of Nextcloud is not compatible with > PHP 8.0. You are currently running 8.1.10.

I can open panel, mine is set to port 4444, and see this. There isn't much in it.

When I get to the web UI, mine is set to port 444, I get this message:
This version of Nextcloud is not compatible with > PHP 8.0.
You are currently running 8.1.10.
