Hello! I see you're encountering the "Query has failed" error with the PlantNet app. To help you better, could you tell me when exactly you see this error? For example, is it when you try to upload a photo, search for a plant, or some other action? Also, are you using the mobile app or the web version of PlantNet?

Meanwhile, here’s a general approach to fix such query failure errors, which usually relate to issues with the app communicating with the server or database:

1. Check Internet Connection: Ensure your Windows device has a stable internet connection. An unstable or slow network can cause query failures.
2. Restart the App: Close the PlantNet app entirely and reopen it. This can refresh the connection to the server.
3. Update the App: Make sure you have the latest version of PlantNet installed. Updates often fix bugs causing query problems.
4. Clear Cache / Data: If using a browser, try clearing cache and cookies or using an incognito window. If using the app and it supports clearing cached data, do that.
5. Check Firewall/Antivirus: Sometimes, security software can block the app's data queries. Temporarily disable firewall or antivirus and test if queries succeed.
6. Try Another Network: If possible, connect to a different WiFi or use a mobile hotspot to rule out network-specific blocks.
7. Log Out and In: If the app has an account system, logging out and back in can reset session tokens that might be causing query issues.
8. Reinstall the App: Uninstall PlantNet from your Windows device, then reinstall it fresh.

If none of these work, the issue could be with the PlantNet servers or an application bug. Then, I would need to help you with further diagnosis or escalate it to our technical team.

Could you try these steps and let me know which ones you’ve done or if you need detailed guidance on any step? That will help me tailor the solution precisely for your setup.
