SKErrorDomain Code=0 in In-App Purchase

Question

Today, when testing IAP in sandbox mode, we suddenly got SKPaymentTransactionStateFailed with Error message:

Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store" UserInfo={NSLocalizedDescription=Cannot connect to iTunes Store}

Then the alert comes

It works before, we did not change any IAP related Code.

I have searched stackoverflow and google and tried these:

• Test with device, not simulator,
• Make sure product id is right.
• Make sure the build number in XCode General Settings is right
• Create new sandbox test account in iTunes connect, and logout all other account, then test with sandbox test account.
• Reboot/Reset the device
• Make sure apple developer account is not renewed recently

None of these works for me. Any suggestions？

Update: I think it is the iTunes Connect Server problem, it is solved now.

Answer 1

There seems to be a bug going on just now. Our logs show increased errors in both production and sandbox. So far we haven't seen any solution yet.

--Edit--

This has been fixed.

Voting to close this issue to prevent confusing future similar problems.
