After two days I've finally managed to solve my problem. Thanks to this page

I've ended up deleting the /etc/nginx/sites-available/default file and I have only one apache file.

Just following the instruction in the page where it says enter your ip address you can enter 127.0.0.1 if you are only trying to set it up for your local env.

Also you can skip 8 part and follow other parts as you don't need them. Those are for setting up so your server/com can be visible outside of our network so to call - Internet :)
