    It sounds like this is not an Nginx problem. Do you see any access attempts in the Nginx access or error logs? You should if it’s an Nginx issue.

    Your netstat output shows that Nginx is running and listening on Port 80 on all IPs.

    Try using nmap to port scan yourself and confirm something running on port 80 is detected:

    nmap -vv -P0 (server IP address or DNS)

    If it doesn’t find anything, it sounds like it’s being blocked somewhere else. Talk to your network administrator.
