Nginx reverse proxy with TLS

[alzhyganshal]

Thanks for your websocket tunnel implementation!

I've wanted to run it behind NGINX reverse proxy with TLS.

nginx config part:

location /ws_proxy/ {
            proxy_pass http://127.0.0.1:8080;
            proxy_buffering off;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
            proxy_set_header        Host            $host;
            proxy_set_header        X-Real-IP       $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header        X-Forwarded-Proto $scheme;
#access_log off;
        }

TLS is enabled, and it's running on 443 standard HTTPS port.

wstunnel server is running like this: wstunnel server --restrict-http-upgrade-path-prefix ws_proxy ws://[::]:8080. Logs:

There is nothing on Nginx access or error logs. Long story short it is not working behind Nginx. Am I missing something?
