Description

There is a mistake in manual in chapter with code snippet:
"location /chat/ {

proxy_pass http://backend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

}"

In last line we need to change first character from 'u' to 'U' in word "upgrade". I have wasted two days to find this problem.

With this problem I had 504 error from websocket-server, when I tryed to proxy websocket with ssl. Only difference between direct datapacket and proxyied packet show me the problem. In russian version of manual i had the same problem.

This looks like a bug in your websocket-server.

As per Section 6.1 of RFC 7230:

Connection options are case-insensitive.
