I was experiencing this exact issue - QR code never appears, connection keeps looping.

I manually applied the fix from PR #2365 and it works perfectly. Here's what I added in src/api/integrations/channel/whatsapp/whatsapp.baileys.service.ts around line 429, inside the connection.update handler before the reconnection logic:

// FIX: Do not reconnect if its the initial connection (waiting for QR code)
const isInitialConnection = !this.instance.wuid && (this.instance.qrcode?.count ?? 0) === 0;
if (isInitialConnection) {
this.logger.info("Initial connection closed, waiting for QR code generation...");
return;
}

The problem: When Baileys closes the connection during initial setup (before QR scan), the code was triggering a reconnection loop instead of waiting for the QR to be generated.

The fix: Skip reconnection if it's the initial connection (no wuid yet and QR count is 0).

Tested on v2.3.7 - QR code now generates correctly and WhatsApp connects after scanning.

Hope this helps get it merged! 🙏

As #2388 suggests, I added this to my docker-compose.yml when deploying it on Coolify:

    environment:
      - NODE_OPTIONS=--network-family-autoselection-attempt-timeout=1000

This increases the timeout and the Qrcode is displayed now.
