Hello!
I have nodebb forum. And recently I move ns server to cloudflare to get free SSL certificate for my domain.
But, unfortunately CloudFlare does not support web socket.
Here is a ticket

All other customers -- Business, Pro, and Free -- should create a subdomain for Websockets in their CloudFlare DNS and disable the CloudFlare proxy ("grey cloud" the record in CloudFlare DNS Settings).

Is there is a way to left forum on cloudflare enabled domin, but move socket.io websocket domain onto subdomain with disabled cloudflare service?
