General idea of the config
https + proxy pass + virtual host
Nginx as a proxy causes a failure of wss:// connections to the backend server.
add these parameters to the proxy section :
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection “upgrade”;
proxy_set_header Host $host;
Voila’ !!!
