Nextcloud with nginx and php-fpm without ssl

Nextcloud version (eg, 20.0.5): 23.0.2-1
Operating system and version (eg, Ubuntu 20.04): Arch Linux 5.16.12-arch1-1
Apache or nginx version (eg, Apache 2.4.25): nginx version: nginx/1.21.6
PHP version (eg, 7.4): php -v PHP 8.1.3 (cli) (built: Feb 16 2022 13:27:56) (NTS) Copyright (c) The PHP Group Zend Engine v4.1.3, Copyright (c) Zend Technologies with Zend OPcache v8.1.3, Copyright (c), by Zend Technologies

I want to install local and test the config before I do behind a HAproxy, so the local config should be on a local IP.

I get a 404 Error with nginx and no entries in error or nextcloud log

So i didn’t really find a vhost for nginx and port 80

1.Is this vhost ok?
2. Can I open nextcloud only with a IP or is a domain necessary?
3. If a domain is necessary how would you setup a local domain behind HAproxy?
