Hello! I understand you're having trouble connecting to the 3D Warehouse through the Trimble Connect app. Let me help you get this sorted out.

To start, can you tell me if you receive any specific error messages when trying to connect to 3D Warehouse? Also, is this issue happening only on your WebKit browser on Windows 10, or does it occur on other devices or browsers as well?

Meanwhile, here’s a step-by-step approach you can try to resolve the connection issue:

1. Check Internet Connection: Make sure your network is stable and that other websites or online services load properly.

2. Restart Your Browser and App: Close your browser completely and reopen it, then try accessing the 3D Warehouse again. Sometimes a simple restart clears temporary glitches.

3. Clear Browser Cache: Cached data can cause loading problems. Clearing your browser’s cache and cookies can help refresh connection links.

4. Verify Sign-in Status: Confirm that you are signed in properly to your Trimble account in the Trimble Connect app and in the 3D Warehouse service.

5. Check Firewall or Antivirus Settings: Sometimes these security programs block connections to online repositories like 3D Warehouse. Make sure they allow access to Trimble and SketchUp online services.

6. Update the Browser: Ensure your version of WebKit (or the browser it belongs to) is up to date, as outdated versions can lead to compatibility problems.

If you've already tried these steps, please let me know which ones, and if you noticed any error messages, so I can guide you further. We can also explore advanced settings or check for any reported outages impacting 3D Warehouse connectivity.
