Nginx : Cannot listen on port 80 ... only port 8080 works on OSX 10.11

OSX 10.11 I installed the latest nginx 1.9.9 (from source and compiled ) the configuration file /usr/local/conf/nginx.conf syntax is ok

when listening on port 8080 no problem I can request http://example.local:8080

server {
    listen       8080;
    server_name  example.local;
    root HTML;

And then run:

 sudo lsof -i -P | grep -i "80"
 nginx     8254           root   10u  IPv4 0x643a3abbad7bf485      0t0     TCP *:8080 (LISTEN)
 nginx     8392           yves   10u  IPv4 0x643a3abbad7bf485      0t0    TCP *:8080 (LISTEN)

BUT when I change the port to 80, I cannot reach http://example.local:80

server {
    listen       80;
    server_name  example.local;
    root html;

sudo nginx -s reload
nginx     8254           root   10u  IPv4 0x643a3abbad7bf485      0t0    TCP *:8080 (LISTEN)
nginx     8254           root   18u  IPv4 0x643a3abbadbb9485      0t0    TCP *:80 (LISTEN)
nginx     8430           yves   10u  IPv4 0x643a3abbad7bf485      0t0    TCP *:8080 (LISTEN)
nginx     8430           yves   18u  IPv4 0x643a3abbadbb9485      0t0    TCP *:80 (LISTEN)

Safari canot open the page however I can still request http://example.local:8080

Run top in your the terminal and use F3 to search for the NGINX process. Copy the PID number from the running NGINX process when you find in the top list running process. Paste the PID number into /usr/local/nginx/logs/nginx.pid. Just paste in the PID number on it's own on the first line of the nginx.pid file. Even if already stopped it before STOP nginx sudo nginx -s stop and then start it again sudo nginx.

Nginx can't stop it's process because it doesn't know the PID number and the running instance is bound to the relative port blocking a second instances binding to the same port.

This was on MacOS Ventura, a fresh install. It happened because I changed the location of the PID file in the NGINX config file while it was running and therefore it couldn't stop itself.

Check firwall or iptables.

Port 80 might be blocked. Try stopping firewall or iptables service.

If it is blocked, then add entry to allow port 80

You just can run services on ports below to 1024 as sudo.

Running on the go:

$ sudo brew services restart nginx

Starting with the system:

$ sudo cp /usr/local/opt/nginx/*.plist /Library/LaunchDaemons
$ sudo launchctl load -w /Library/LaunchDaemons/homebrew.mxcl.nginx.plist

Note that you must set up your server to listen to 80 inside your config file and make sure there's no other process running at port 80.
