Hi,

I am struggling in order to setup nginx as reverse proxy with HTTPS.
In current test setup I installed nginx on a CentOS 7 machine (host 192.168.1.115) and apache within a docker container.
Everything works fine as long as I use HTTP only.
However if I enable SSL, my browser always ends up in getting response code 400 (bad request).

ssl_certificate "/etc/nginx/cert.crt";
ssl_certificate_key "/etc/nginx/cert.key";
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 1m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;

server {
listen 443 ssl;
server_name .hello.com;

location / {
proxy_pass http://127.0.0.1:8000;
}
}

In error.log I read:

2017/10/04 17:40:06 [info] 5695#0: *27 client sent invalid request while reading client request line, client: 192.168.1.120, server: , request: "CONNECT alpha.hello.com:443 HTTP/1.1"

On the other hand, if I run in a terminal:

openssl s_client -connect 192.168.1.115:443

and then I enter

GET https://alpha.hello.com/

I get the expected content (in this case error.log just prints
2017/10/04 18:15:41 [debug] 15843#0: *40 http request line: "GET https://alpha.ciao.com/"
)

By the way, I tried different browsers, but the proxy configuration should be pretty simple: I always set 192.168.1.115:443 as HTTPS/SSL proxy or as proxy for all protocols (actually I aim to use HTTPS only)

What is my mistake? Is anything missing in nginx configuration? Is there a proxy setup in the browser I am not aware of?
