Needing help to get nginx to listen on port 80

Posted on June 23, 2020

Ive setup nginx for the first time on Ubuntu 20.4 following the guide https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-20-04 - in preparation for a wordpress install - but I cant get the server to respond to http requests - nginx status reports its active and running - and ufw status also reports port 80 is open - Ive reset the firewall using this guide https://www.digitalocean.com/community/questions/how-to-reset-the-firewall-on-ubuntu and attempted again to enable http but no joy - this port scanner tells me the port is closed https://www.ipvoid.com/port-scan/ which explains why no response for http requests but how to open it is my problem.

Hi @greencomputing,

It’s possible you have the Nginx listening on another port rather than 80. What I’ll recommend is first identifying the port Ningx listens to. Open an SSH session to your droplet.

Once in, type in the following command

netstat -tulpen

It will show you all ports that are being used by a service. See if Nginx is actually listening to port 80 and 443. If it’s not you’ll need to change that. This can be changed from the default Nginx configuration file which should be available in /ec/nginx/.

Once you change the port, don’t forget to restart Nginx
