Nginx Configuration for websocket: Error during WebSocket handshake: Unexpected response code: 403

[raphy]

Hi Sergey

The nginx configuration I used for /xmpp-websocket location, taken from
here: https://prosody.im/doc/websocket , follows the official nginx
indications: https://nginx.org/en/docs/http/websocket.html

If nginx doesn't support bootstrapping WebSockets with HTTP/2, what should 
I do?
