Fresh install of snap nextcloud doesn't work via http

Nextcloud version:
Operating system and version: Ubuntu server 20.04.3
PHP version: 7.4.23

Can someone suggest me what’s happening? I really don’t get it.

  • I installed snap version of nextcloud on ubuntu server;
  • Router port forwarding 80 and 443 is pointing to internal nextcloud server IP;
  • ports 80 and 443 are allowed by ufw;

I was never able to access nextcloud via http and of course i couldn’t obtain a certificate by let’s encrypt; nevertheless I installed a self signed certificate and everything works good when I access nextcloud via https.

Other details:

  • change the port for http doesn’t resolve the problem;
  • if I try to reach nextcloud using the server local ip address or with the domain name associated with it I have the same results

This is my config file:
