2173	Nginx simple proxy set-up returns 400 (Bad Request)	Aniruddha Gore		"**Context:**
I have my client application running on a machine (A) that does not have internet connectivity. It, however, can connect to another machine (B) that has full network connectivity. I intend to set-up nginx as a simple proxy on B such that the client app on A can make HTTPS requests by setting web proxy on them (B's ip address and port).

**Problem:**
All requests fail with 400 with following in error.log:
*1 client sent invalid request while reading client request line, client: ###.###.#.##, server: , request: ""CONNECT my.service.url.com:443 HTTP/1.1""

**Config:**
This is how nginx.config looks like:

worker_processes  1;
error_log  logs/error.log  info;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       8080;
        location / {
            proxy_pass https://my.service.url.com:443;
        }
    }
}

**Questions:**
I am not sure why requests keep failing. I am new to the world of proxy so any help in the right direction is really appreciated. I suspect this is happening because I did not understand the config correctly, or, something to do with the calls being HTTP**S**."	task	closed	minor		other		invalid			N/A	"nginx version: nginx/1.20.0
