Question

I got a problem that I don’t know how to fix it. Please help!

When my app tries to purchase in sandbox, it always receives the error SKErrorUnknown. I have tried the ways mentioned in these threads but not work for me:
Apple In-App Purchase
SKErrorUnknown while testing in-app purchase

I searched on google but still no help.

Does anyone know how to fix it?

1. The app can get the product from AppStore successfully.
2. The confirm dialog appears.
3. After I click the “Buy” button, the app receives the error.
4. The description of the error is “Cannot connect to iTunes Store.”
5. I’m using XCode4.2

After I searched and tried for a whole day, finally @orazran gave me the answer:

JUST CREATE A NEW TEST ACCOUNT.

If anyone meets the problem again, please try this simple step first.
