DNS_PROBE_FINISHED_NXDOMAIN error while accessing Looker Developer: Qwik Start (GSP891) lab URL

Hello Google Cloud team 👋

While performing the **Looker Developer: Qwik Start (GSP891)** lab on [Qwiklabs / Cloud Skills Boost](https://www.cloudskillsboost.google/), I encountered a **“This site can’t be reached”** error when trying to open the generated Looker resource link.

The error displayed in the browser was:
```
DNS_PROBE_FINISHED_NXDOMAIN
```

---

### 🪜 Steps to reproduce:
1. Start the Looker Developer: Qwik Start (GSP891) lab.
2. Complete the setup and wait for the Looker instance to start.
3. Click on the generated Looker instance URL — it points to something like:
```
https://uto72ax6yizujyavk6sxwuinjycpuwqlpllaeiaa4ytx7gvfifq.us-east1-b.resources.bumper-boats-00.services.qwiklabs.com
```
4. Browser returns a “This site can’t be reached” error.

---

### ✅ Expected behavior
The Looker instance should launch successfully and display the Looker web interface.

---

### ⚠️ Observed behavior
The domain is not resolvable — the DNS record seems missing or expired before lab resources became available.
