If the connection attempt gets to nginx, the nginx logs can show something
about it.

But it looks to me like your security system is preventing the request
getting to nginx in the first place. Check your firewall or other network
control logs to see what is happening.

nginx is not a proxy. So no request that comes to the server will involve
"curl -x" with the nginx host:port. As far as any client is concerned,
nginx is a web server.

Good luck with it,
