Can't access openproject from outside local

Question

I've installed openproject on ubuntu 22.04.3 with apache2, and i can only access it locally.

apache2/ports.conf:

If you just change the port or add more ports here, you will likely also 
have to change the VirtualHost statement in
/etc/apache2/sites-enabled/000-default.conf

Listen 0.0.0.0:80

<IfModule ssl_module>
Listen 443
 </IfModule>

 <IfModule mod_gnutls.c>
Listen 443
 </IfModule>
 vim: syntax=apache ts=4 sw=4 sts=4 sr noet

apache2/sites-available/openproject.conf:

Include /etc/openproject/addons/apache2/includes/server/*.conf IncludeOptional /etc/openproject/addons/apache2/custom/server/*.conf
<VirtualHost *:80>
ServerName 127.0.1.1
DocumentRoot /opt/openproject/public
ProxyRequests off
Include /etc/openproject/addons/apache2/includes/vhost/*.conf IncludeOptional
/etc/openproject/addons/apache2/custom/vhost/*.conf
# Can't use Location block since it would overshadow all the other proxypass directives on Centos ProxyPass /openproject/ http://127.0.0.1:6000/openproject/ retry=0
ProxyPassReverse /openproject/ http://127.0.0.1:6000/openproject/
</VirtualHost>

sudo netstat -tuln | grep 80:
