store kit transaction error: "Cannot connect to iTunes Store" on ios 7 device

Question

On product request I am getting all the products. I am also getting the product buy alert in below ios 7 devices but not for the ios 7 and above.

For ios 7 and above I am getting an error as:
Transaction error: Cannot connect to iTunes Store

I am running app on the device itself and not on the simulator. I have gone through other SO as well but unable to rectify my problem.

Please help.

Answer 1

I had the same issue. Here is similar question I am getting error while requesting products from App Store for IAP

Try doing this:
1)You have to test on device
2)Go to setting -> iTunes & App Store -> and log out of your account.
Remove app from device and clean all data.
Make sure you have done all necessary steps for in-App purchase testing. Here is apple documentation
Run on device and test it.

If you having similar issue, please, check that you do not have expired contracts in itunesconnect.
