Socket.IO Error 400


I have an https server running on port 443. I’m trying to connect via to a WebSocket on port 8443.

Every time I get WebSocket connection to 'snip' failed: Error during WebSocket handshake: Unexpected response code: 400

Is there something in cloudflare that would be affecting this? I’ve made page rules to turn security to very low on port 8443.


I don’t use Websockets, but I do know there’s a setting in the Cloudflare Dashboard under the Network tab. Is your Websockets feature enabled?
