Unable to Sign In - Server error status code: 403, 'forbidden'. GoPayment installed on IOS 12.5.7 does not work. I can login to merchant center on Win 11 PC.

Hello there, Bensonix. Let's perform some troubleshooting steps to help you log in to your GoPayment app and then redirect you to the best support who can help check your account for possible credits.

To begin, we can update your QuickBooks GoPayment and Online mobile app. Doing so will make sure you have the most recent upgrades of the application. To do this on your iOS, follow these steps:

1. Launch your App Store, then select Updates.
2. Select Settings, then General.
3. Tap Software Update.

After that, open and log in to the GoPayment app. If you continue to get the same result, uninstall and reinstall the application to start afresh.

On the other hand, I recommend contacting our support team. They have additional tools to pull up your account and further review the problem.

Here's how:

1. Log in to your QBO company.
2. Select Help (?).
3. Click Contact Us and choose a way to connect with us:

• Start a chat with a support expert.
• Get a callback from the next available expert.

In addition to this, I'm sharing this handy resource to help you fix GoPayment issues and handle payments if you have a QuickBooks Online mobile app: Fix issues with GoPayment and QuickBooks mobile app card reader.
