can't reach Nextcloud setup with with Docker

Hi all,

I need some help with this Nextcloud-Docker seutp.
I followed this tutorial: https://www.youtube.com/watch?v=PKsq7k2pwsI, but I can't reach the Nextcloud initial setup page.
I already did the port forwarding in my router.

Router: 443>444
80>8080

Docker: 444>443
8080>80

I'm trying to connect like this: https://192.168.1.12:444

error:

Your connection is not private
Attackers might be trying to steal your information from 192.168.1.12 (for example, passwords, messages, or credit cards). Learn more

I don't have the option to click on.

I managed to reached the setup page by used Safari on Macbook.
Don't know why I can't access it through Google Chrome.

I've activated the LetsEncrypt, and now I can't access Nextcloud with either URL or local ip address.

config.php

<?php
$CONFIG = array (
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'datadirectory' => '/data',
  'instanceid' => 'ocndbp9ir3ip',
  'passwordsalt' => 'xxxxxxxx,
  'secret' => 'xxxxxxxxx',
  'trusted_domains' =>
  array (
    0 => '192.168.1.12:444',
    1 => 'cloud.xaaa.com',
  ),
  'overwrite.cli.url' => 'https://cloud.xxxxs.com',
  'overwritehost'     => 'cloud.ixxxa.com',
  'overwriteprotocol' => 'https',
  'dbtype' => 'mysql',
  'version' => '17.0.1.1',
  'dbname' => 'nextcloud',
  'dbhost' => '192.168.1.12:3306',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'admin',
  'dbpassword' => 'xxxxx',
  'installed' => true,
);

server {
    listen 443 ssl;
    listen [::]:443 ssl;


    server_name cloud.*;


    include /config/nginx/ssl.conf;


    client_max_body_size 0;


    location / {
        include /config/nginx/proxy.conf;
        resolver 127.0.0.11 valid=30s;
        set $upstream_nextcloud nextcloud;
        proxy_max_temp_file_size 2048m;
        proxy_pass https://$upstream_nextcloud:444;
    }
}

I notice that somehow it trying to use the Linuxserver.io's cert instead of LetsEncrypt.
I'm using no.ip.org though.

I changed some settings, and now I'm getting error when try to access Nextcloud: 'Welcome to Our Server...The website is currently..."

I changed the port, but still the same error: "Welcome to our server...."
If the Nginx plugin is available in OMV5, I would done this a long time ago.

I think so, it using bridge network.

If I have the following settings in the Portainer then nothing is working:

LetsEncrypt docker:
network: my-net
command: --add-cap=NET_ADMIN' '--network my-net'

Nextcloud docker:
network: my-net
command: '--network my-net'

If I removed the extra command parameters, and set the network as 'my-net', then I can access via URL, and https://192.168.1.12:444/login.
I'm getting close.

What am I missing here ?

Am I suppose to use https://local.ip:444 or https://local.ip:450 ?
