Issue to open Cloud Memorystore – Chapter 3.16

I hasn’t possible to visualize the video "https://learn.acloud.guru/course/gcp-certified-professional-data-engineer/learn/b404afd2-7ff2-5d28-27e0-e9e04743d738/d1b23cb8-6e77-b855-a25d-c00429b21530/watch", first video of chapter 3.16. Can you help me ? Important point: the others (like 3.17) are executed normally.
