Apache2 page is diffrent when accessed out side of the network

Hi im new here i hope you can help me with this issue
so i have a no-ip domain lets say its "test.ddns.net" and i have the no-ip client on my linux (kali)
i started apache2 service, when i go to "localhost or the test.ddns.net " i get my website which is in /var/www/html/index.html
but when im trying to access it from a device out side the network im getting 403 Forbidden nginx

 

Not sure if that's what you're looking for, but here it is:

no i already have port forwarding and i can access my host but im getting 403 Forbidden web page

 

+Update:
i tried configuring some files, now when i try to get to my website from out side the network i get default apache2 page instead

 

Do you have Apache virtual host for your domain pointed to the appropriate document root directory?

 

It could be due to the wrong index file. Try auto indexing by
autoindex on;
autoindex_exact_size off;
These configurations must be added to a location block.
