Hi, I’m experiencing this issue where web socket connection can be established locally. But when trying this in a deployed Cloudflare Worker, I’ve got the following error:
Error: Uncaught TypeError: Failed to establish the WebSocket connection: expected server to reply with HTTP status code 101 (switching protocols), but received 404 instead.
I receive 404 when using wss
& 520 when using ws
It seems like access from Cloudflare is blocked?
