I have Nexcloud AIO on Docker on Ubuntu 24.04.
Portainer is running, and it reports MariaDB is also.
When I start Nextcloud AIO I get this error:

Failure

I found that apache was running on port 80 on the host, so changed port to 81. I can access it at ip: 8080.. however now after logging it is asking for domain. Can I not access it from IP:8080?
It says:

New AIO instance

AIO is currently in “normal mode” which means that it handles the TLS proxying itself. This also means that it cannot be installed behind a web server or reverse proxy (like Apache, Nginx, Caddy, Cloudflare Tunnel and else). If you want to run AIO behind a web server or reverse proxy (like Apache, Nginx, Caddy, Cloudflare Tunnel and else), see the reverse proxy documentation. Advice: have a detailed look at the changed docker run command for AIO.

Please type in the domain that will be used for Nextcloud and submit it.

:8080 is the management interface for AIO

Nextcloud Server itself will be reachable via https://yourdomain.com:443 at the domain you configure.
