Nginx Error – bind() to 0.0.0.0:443 Failed (48: Address Already in Use)

I have Laravel Valet 2.1.6 installed on Mac OS 10.14.2.

nginx 1.15.8 is installed using brew.

I restarted my Mac without installing any updates or new software, and now all example.test sites are giving a 502 error with the following showing in the /usr/local/var/log/nginx/error.log log:

2019/01/17 20:38:47 [warn] 31277#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /usr/local/etc/nginx/nginx.conf:1

2019/01/17 20:38:47 [emerg] 31277#0: still could not bind()

At the same time, I get the following in the /Users/Myself/.config/valet/Log/nginx-error.log log:

2019/01/17 20:41:34 [error] 32071#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 127.0.0.1, server: example.test, request: "GET / HTTP/2.0", upstream: "fastcgi://unix:/Users/Myself/.config/valet/valet.sock:", host: "example.test"

When I run ps ax -o pid,ppid,%cpu,vsz,wchan,command|egrep '(nginx|PID)' I see this list:

None of the following solves the issue:

• sudo killall nginx
• brew services restart nginx
• brew services restart php
• valet restart
• Restarting my Mac
• valet uninstall && valet install then valet park on the relevant dir

Apache is not running as a conflicting service.

I tried doing sudo /usr/local/opt/nginx/bin/nginx -g 'daemon off;' and got this:

nginx: [emerg] still could not bind()

Running sudo lsof -i tcp:80 produces:

Basically the same output when I run that command for port 443.

This valet issue post suggests valet domain test might fix it, but that didn't help.

Tried reinstalling PHP but no luck:

• brew uninstall –force php
• brew cleanup
• brew install php
• valet uninstall && valet install

Tried deleting all valet config/certificate directories, uninstalled valet again, then reinstalled and re-parked my project dir.

Tried running nginx as root:

• sudo brew services stop nginx
• Confirmed nothing is running on port 80 and no nginx processes
• sudo brew services start nginx
