Hi! I understand you're getting a "check your connection" message when trying to log in with your DigiD app, even though your internet seems fine. Let’s work through this together to get you logged in smoothly.

First, can you tell me if you’re using Wi-Fi or mobile data? Also, is your DigiD app updated to the latest version? Sometimes outdated apps can cause connection issues despite having internet access.

Meanwhile, here are some steps to try:

1. Restart your device: This refreshes your connection and the app environment.

2. Check internet connectivity: Even if other apps work, DigiD might have trouble if the connection is unstable. Try visiting a webpage in your browser to confirm.

3. Switch network: If on Wi-Fi, try switching to mobile data or vice versa, just to rule out network-specific issues.

4. Clear app cache and data: On Windows and WebKit browsers, clear the browser cache or app data to remove potential corrupted files.

5. Reinstall the DigiD app: If you’re using the standalone app, uninstall and reinstall it to ensure all files are intact.

6. Check firewall or antivirus: Sometimes security settings may block app access. Temporarily disable them to test login.

After trying these, let me know if the message persists. That way, I can help dig deeper if needed. Are you currently seeing any other error codes or messages beyond "check your connection"?

Looking forward to your reply!
