Question

Nginx is unable to bind to 443

Hi all, I have been trying to bind my nginx to port 443. The config file works fine however when i type sudo nginx i repeatedly get address is in use on the bind. I have then used netstat which claims nginx is using the port yet nginx is actually saying it’s not binding.

/etc/nginx/sites-available$ sudo netstat -pan | grep “:443” tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 3448/nginx /etc/nginx/sites-available$ sudo nginx nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] still could not bind()

I have killed all Nginx processes and started up a new nginx copy. rebooted the server to no avail…

Any ideas on what i can do next?

Thanks

Case Closed: You need to create an upstream proxy to get node.js to proxy via Nginx.
