In App Purchase stopped working (error code 109)

Question

When today I tested my In-App purchases again (on a device) it gives me the following error (when I fetch the available products of my app):

Cannot conn

Answer 1

1) On the first device I also got this error while requesting SCProducs in the sandbox environment.

2)I have tried to request SCProducs from another device. This error hadn't appeared.

3)After that on the first device I have "Erased All Content and Settings" logged in and out from the real "iTues & App Store" account, launched the app and this error hadn't occurred. (Maybe just coincidence)

!!! Interesting investigation. After I set the Date & Time for an hour earlier (on another device - for a day earlier) the SKProducts come as they have to.
