Failure during payment with sandbox account

I got this error if I buy my IAP on the simulator with a sandbox account. Any solutions? On android it's working very well.

<SKPaymentQueue: 0x6000018b8430>: Payment completed with error: Error Domain=ASDErrorDomain Code=530 "(nu11)" UserInfo={NSUnderlyingError=0x600001512970 (Error Domain=AMSErrorDomain Code=100 "Authentication Failed The authentication failed."

Which necessary steps are required to upload an app with IAP to the app store? I got the message from the review, that I need to upload a video on a physical device, which shows the iap process. But I don't have a physical device and at the time of my first upload a video wasn't required.

I developed my game in Unity with Codeless IAP integration. Thanks for response.

That is the expected behavior. In the sandbox, you can fetch in-app purchase information in the Simulator. However, you cannot purchase them. To test purchasing in-app purchases in the sandbox, run your app on a device. Be sure to use sandbox Apple accounts. For more information, see Testing In-App Purchases with sandbox .
