sudo a2ensite default-ssl.conf
sudo service apache2 restart

sudo nano /etc/apache2/sites-available/000-default.conf
delete everything and added

sudo nano /var/www/html/nextcloud/config/config.php
’trusted_domains’ =>

1 => ‘public ip adress’,
3 => ‘public ip adress phone network’,

overwrite.cli.url =>
dbtype mysql

I installed nextcloud in /var/www/html/nextcloud

portforwarded on my router 443 and 80

when I delete see below http connection nextcloud from public IP works
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,L]

How can I fix it that nextcloud is access able from my public IP adress on https. I tried many things changed overwrite.cli.url from http to https. Changed inside 000-defaults.conf many things.

isn’t that supposed to be <VirtualHost ip_or_*:443>

Since you created a snakeoil cert, why not just leave the snakeoil in? You will get a certificate error anyways when you browse to it, but i guess (hope) you are just testing and figuring things out.

If you can https browse it from LAN but not from WAN i´m 100% certain, that the problem doesn’t lie within your nextcloud server or webserver config, but on your router/firewall or somewhere else outside your NC Server.

Can you access the default index file of webserver root via https from outside network? What message does browser show?
Perhaps also webserver log provides hints.

Common Name (e.g. server FQDN or YOUR name) []: pressed enter

Did you enter public IP/domain there? At least otherwise this would produce browser warnings.

443 is given in default-ssl.conf, 000-default is the correct 80 vhost that just provides the redirection.

Thanks you guys the problem was my firewall 443 was restricted i changed it to 8443
