I am a first-timer with this stuff. I have a new Ubuntu server. I have PostFix and SSH working.

I have installed Wordpress (Lamp stack, apache2, and MariaDB). I also installed NextCloud and uninstalled it again.

Now, Localhost shows my wordpress site just fine. But my static IP and domain name do not.

When I go to my static IP:

Unable to connect
Firefox can’t establish a connection to the server at [Static ip here].

When I go to my domain name:

Hmm. We’re having trouble finding that site.
We can’t connect to the server at [domain name].

It is always hard to know what data to present here. But from other posts (I have tried to follow them but to no success) I see some stuff, I'll add it, but please ask if you need more.

iptables -L -n | grep 80

ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80

a2dissite command only shows my own domain.

my config for the domain (is in sites-enabled)

<VirtualHost *:80> ServerName [domain name] ServerAlias name] ServerAdmin [my mail] DocumentRoot /var/www/[domain name] <Directory "/var/www/[domain name]"> Options FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

I feel I have tried many things now, but I cannot seem to find the right post to guide me to the answer.

One final thing is that my domain name is .dk, I do not know if that changes anything, but now you know.

I hope you can.

The ISP had reset the router settings (apparently does that once a year on default), so my static IP had changed.
