Hi there! I understand you're getting a "Couldn't connect to server" message whenever you try to use any function in the KitchenPal Shared Grocery List app. Let's work together to get this sorted out.

To start, could you please tell me if this is happening all the time or only when you try specific actions? Also, are you connected to the internet via Wi-Fi or mobile data on your Windows device using WebKit browser?

Meanwhile, I’ll guide you through some steps to check the most common causes:

1. Check Internet Connection: Make sure your Windows 10 device is properly connected to the internet. Try visiting unrelated websites to confirm internet access.

2. Refresh the App/Browser: Since you’re using a WebKit browser on Windows, try closing the browser completely and reopening it. Then reload KitchenPal to see if it connects.

3. Clear Browser Cache: Sometimes cached data can cause connection problems. You can clear your browser cache/settings and then retry.

4. Disable VPN or Proxy: If you are using a VPN or proxy, temporarily disable it as this might interfere with server connection.

5. Check for Firewall or Antivirus Conflicts: Your Windows firewall or antivirus software might block access. Verify that KitchenPal or your browser is allowed through.

6. Server Status Check: Occasionally the KitchenPal servers may be down for maintenance or experience issues. While I don’t have a live status link, if the problem persists after these steps, we can consider this possibility.

Let me know if you have already tried any of these or if you see any changes after trying them, so I can assist you further! Are you connected to the internet normally outside of KitchenPal?
