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* LISTEN 3448/nginx /etc/nginx/sites-available$ sudo nginx nginx: [emerg] bind() to failed (98: Address already in use) nginx: [emerg] bind() to failed (98: Address already in use) nginx: [emerg] bind() to failed (98: Address already in use) nginx: [emerg] bind() to failed (98: Address already in use) nginx: [emerg] bind() to 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?

sudo fuser -k 443/tcp service nginx restart

What happens when you run sudo fuser -k 443/tcp? I am working with Docker running Nginx get that error inside the container. I cannot run that command because my Docker items run on 443. How do I fit the error in a Docker Container?
