Hi there! I see you're having trouble logging in to the parking app. Let's get this sorted out together. To better assist you, could you tell me if you're seeing any error messages when trying to log in? Also, are you logging in with your email address or phone number?

Meanwhile, here's a general approach we can try to fix login issues:

1. Double-check that you are entering the correct email address or mobile phone number associated with your account in the username field. Sometimes a small typo can cause login failure.

2. Make sure your internet connection is stable—try opening other websites or apps to confirm connectivity.

3. Restart your device to clear any temporary glitches that might be affecting the app.

4. If you’re using the One Parking app via a browser on your Windows device, try clearing your browser cache and cookies, then restart the browser.

5. If the issue persists, uninstall and reinstall the parking app to ensure you have the latest version and a clean install.

Do any of these steps sound like something you've already done? If so, let me know which ones, and we can go deeper or try other solutions. If you’re getting a specific error message, please share it with me.

Looking forward to your reply!
