random error "cannot connect to itunes store" in app purchase

Question

I have implemented in app purchase in my iPhone application.

But first time while buying product during payment transaction phase I get an error:
cannot connect to iTunes store and it results in unsuccessful payment transaction.

Main thing is that it is occurring randomly means in subsequent attempts transaction gets completed successfully and again after 2 or 3 transactions it gives me the same error.

Weird behaviour?

I have tried all online available solutions like resetting, "Log out" from iTune account and creating new test user account but none is working.

I am trying to solve this problem since last three days(was waiting if problem is from iTune server) but no luck at all.

Before this I have successfully submitted no. of apps having in app purchase. Facing this issue first time.

Please do suggest some solution. Thanks

Answer 1

In my case the error was because of "TimeOutInterval:".

In my In app purchase implementation workflow, in between there was a call to our local server to make entry of subscription in database.

Later I found, because of slow server I was getting late response from server resulting into "requestTimeout".

To solve this problem I increased the timeoutInterval while making request to server. And It worked for me.
