Can't access server_block running on different port than 80 using Nginx

Question

I am trying to run nginx on company server on port other than 80. Since 80 is reserved, I chose port 8082. I need to run it without domain so I could access it using only IP address and port number. Something like this: serverip:8082.

I got it working on my own VPS by configuring server block like this. When i try the same settings on company server, it won't work.

server {
        listen 8082;
        listen [::]:8082;
        ...
}

Some more information

• Server is running on Ubuntu 16.04
• I'm not using server_name in my server block.
• Server block is linked to /etc/nginx/sites-enabled.
• I am using UFW and I have 8082 enabled (ufw is the only firewall enabled on server)
• I see no errors in nginx error log.
• I tried restarting nginx
• I tried editing default server_block to listen on port 8082. Still nothing.
• I unlinked default server_block when trying my own.
• When I run sudo lsof -i TCP:8082 I get result like this:

• My entire server_block

 fastcgi_index index.php;
                fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        }
}

When I try to connect to serverip:8082 It just loads then I get ERR_CONNECTION_TIMEOUT.

Can you help me identify the problem I am facing? I am trying to figure this out since yesterday with no success. Thank you!

Ok so the problem is that there was another layer of firewall outside of VPS which blocked the port 8082. By contacting administrator, he fixed the problem for me and it is now working.
