To Reproduce

1. Run tns preview --bundle
2. Scan QR code from playground app
3. app is not loading in mobile and getting above error on cmd

Beginne damit, den Fehler mit tns preview --bundle zu reproduzieren und den QR-Code in der Playground-App zu scannen. Verfolge den in der Befehlsausgabe angezeigten PubNub-Timeout und ermittle, warum die Preview-App nicht geladen wird; abgeschlossen ist die Aufgabe, wenn die Preview ohne den PubNub-Fehler erfolgreich abgeschlossen wird.
