Nginx Websocket problem <SOLVED>

[michaelgo]

Hi,
latest version
1 upstream server
direct connection to server works just fine including ws
when reverse proxying through nginx (websocket enabled in advanced location settings) ws returns 400
please, help
--
solved by adding in nginx.conf

location / {
   proxy_pass http://$upstream;
   }

I don't know why this is solved if there is no response yet.

However there is a checkbox for websockets. This will set the backend connection to HTTP/1.1 instead of HTTP/1.0.
