iPhone Store Kit “Cannot connect to iTunes Store”

Question

I am working on adding In-App purchases to my app.

I am able to receive the productsRequest:didReceiveResponse method, and receive the array of products

Answer 1

Figured I should share my recent experience with the same issue:

I experienced the same problem a few days ago, where it stopped working from one day to the other. I got the following error after having authenticated with my test user(s): Error Domain=SKErrorDomain Code=0 UserInfo=0x165000 "Cannot connect to iTunes Store"

I hadn't done any changes to the code and we couldn't think of any other changes to our iTunes account or IAP products that might've triggered the problems. The only thing that may have been related was the adding of more iTunes Test Users (although I've added ~15 accounts before without problems). I tested it on different devices and the simulator.

I went through all the available checklists and all possible solutions (everything mentioned above as well) without any success. Finally I figured I might as well take a break from it all over the weekend, since I was drawing blanks. And oddly (and for the first time ever), doing nothing actually worked! I didn't change any code, nor did anything change on our iTunes account or the app.

The only reasons I can think of are:

1. Something was wrong on Apple's end.
2. Some other time-based factor with the app, a certificate or something caused the problems.
3. A leprechaun snuck into my office and fixed the issue.

Answer 2

I was getting SKPaymentTransactionStateFailed error code 0 "Cannot connect to iTunes Store" and thanks to thomax for this answer my problem is solved. Turns out you MUST enter a build number under Targets->Summary.

I spent the last 24 hours resetting my phone, screwing with iTunes connect, and doing just about everything i could think of before i stumbled upon this solution.

Answer 3

Even a full restore did not resolve this problem for me.

After calling addPayment for an auto-renewing product identifier, about one second passed before I received the "SKErrorDomain Code=0" error from StoreKit. At no point was I prompted (as Apple's documentation suggests one should be) for an iTunes Store username and password; the transaction simply failed.

To resolve this, I had to add a fake "consumable" product to iTunes Connect and call addPayment using the fake consumable's product identifier. This caused the iTunes Store dialog to come up. I then logged in with a test account I had created in iTunes Connect. This succeeded: my application was notified that the consumable had been purchased.

After having done this, I was able to call addPayment with my auto-renewing product identifier and purchase the subscription normally.

Answer 4

I assume you've done the standard sanity checks: double-checking your code, confirming your product IDs, comparing your code to the In-App Purchase Programming Guide, etc.

This may be ridiculous, but -- if you're certain your code is correct -- do a hard reset (full wipe) of your iPod (Settings => General => Reset => Erase All Content and Settings). I puzzled over this exact problem for hours -- it turned out my code was correct and the hard reset was the solution.

Answer 5

This is similar to the accepted answer above. I started getting the "cannot connect to iTunes store" error when trying to log in to my iTunes account on my phone after logging in with an IAP sandbox account.

To solve the problem, I was able to just do a Reset All Settings instead of Erase All Content and Settings (Settings => General => Reset => Reset All Settings). Definitely better than having to lose and reinstall everything on your device.

Answer 6

I had the same error, but the problem was not exactly the same. Maybe usefull for someone:

I inserted an external file in the structure of my app. The reason why I did this is because in production, I insert this file dinamicaly from a server, but in development I thought it was faster to use an app called iExplorer to paste this file. I have done this is the past and I didn't have this problem. But in the last few days, if I paste this file directly using iExplorer, my app returns the error: "Cannot connect to iTunes Store". (in spanish: "No puede conectarse a iTunes Store").

I think that it is because this time I inserted the file inside the .app folder. So this makes me think that if you modify your .app folder in any way, the Codesignature breaks and the link with the iTunes Store stops working directly.
