v1.0.0 upgrade fails with `"handshake error: bad \"Upgrade\" header` about ws HOT 6 CLOSED

What is the value of Upgrade header?

@gobwas Hello, I'm getting the same error, when I connect to the WebSocket server using NGINX proxy. Here's how my code looks like,

and NGINX configuration is as below,

location /wsapp/ {
    proxy_pass http://localhost:8080;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Host $host;
}

The problem is when I try connecting to the WebSocket server through Nginx proxy, I'm getting the "handshake error: bad "Upgrade" header error on the WebSocket server side.

Please help!

I still am getting this error in May 2022 (v1.1.0)
