Host a WebSocket server with Cloudflare.

Records preserved for the main Blogger site

The old server record was removed

The imported DNS had an old server record:

A    server    148.72.90.30

That record had to be removed because server.learnwithchampak.live must point to the Cloudflare Worker, not to the old IP.

GoDaddy nameservers were replaced

The GoDaddy nameservers:

ns63.domaincontrol.com
ns64.domaincontrol.com

were replaced with the Cloudflare nameservers:

daniella.ns.cloudflare.com
venkat.ns.cloudflare.com

Basic Worker WebSocket echo code

export default {
  async fetch(request) {
    const upgradeHeader = request.headers.get("Upgrade");

    if (upgradeHeader !== "websocket") {
      return new Response("Use WebSocket: wss://", { status: 426 });
    }

    const pair = new WebSocketPair();
    const client = pair[0];
    const server = pair[1];

    server.accept();

    server.addEventListener("message", event => {
      server.send("Echo from Cloudflare Worker: " + event.data);
    });

    return new Response(null, { status: 101, webSocket: client });
  }
};

What changes?

Before:
https://server.champaksworld.workers.dev/

After:
https://server.learnwithchampak.live/
wss://server.learnwithchampak.live/

Console test

const ws = new WebSocket("wss://server.learnwithchampak.live/");

ws.onopen = () => {
  console.log("Connected");
  ws.send("Champak");
};

ws.onmessage = event => {
  console.log("Received:", event.data);
};

ws.onerror = error => {
  console.log("Error:", error);
};

Expected result

Connected
Received: Echo from Cloudflare Worker: Champak

The static homepage can be served by a Worker response, by Cloudflare Pages, or by another static host. The backend WebSocket behavior comes from the Worker.

server.learnwithchampak.live/
  → Worker handles requests
  → normal HTTPS request returns homepage HTML
  → WebSocket upgrade request becomes WSS backend
