Websocket Port Closed

I’m running Socket(dot)Io server on my EC2 server at 2420 port. When I check port using my server’s IP, its open. But when I test it using domain name, port says closed. How to open the port from Cloudflare so that I can access websocket on my server.

2420 is not a port supported by Cloudflare.

You’d have to use Cloudflare Tunnel for that.
