Looks like to deploy websocket app (such as strfry) behind Cloudflare
I have to use full or strict full for connection between Cloudflare and my server
Ah, Mendokusai
Direct connect: OKAY (Websocket upgraded HTTP status 101)
Proxied via nginx: OKAY (Websocket upgraded HTTP status 101)
Proxied via CloudFlare: Red on noStrudel (Chrome status "Finished")
อืม...ไว้ก่อนละกัน
