nginx missing websocket proxy

Lines 59 to 66 in 57d1b14

	location / {
	proxy_pass $scheme://mainqiita;
	proxy_redirect off;
	proxy_set_header Host $host;
	proxy_set_header X-Real-IP $remote_addr;
	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
	proxy_set_header Accept-Encoding identity;
	}

The provided example nginx configuration seems to not forward websocket HTTP traffic.

W 240215 18:58:08 web:2161] 400 GET /study/list/socket/ (127.0.0.1) 4.57ms
[D 240215 18:58:08 websocket:164] Can "Upgrade" only to "WebSocket".

Should we add a working configuration to this example, such that user do not have to solve this issue by themselves? Btw. I am not sure what the matching configuration would look like, can we follow: https://www.serverlab.ca/tutorials/linux/web-servers-linux/how-to-configure-nginx-for-websockets/ ?
