Have you tried to connect to the App Store and have not been able to?
What a rage it gives!, mainly because you don't know what is happening. A while ago it worked perfectly and now you can't get in.
The reasons why this error appears can be several, including that you do not have a good Wi-Fi connection or that 3G or 4G does not work at that moment, but if everything goes well and that is not the case, from iPhoneA2 we will show you another way to try to fix it.
Fix “Cannot connect to the App Store” error on iPhone or iPad
First of all, open Settings, you know the gray icon in the shape of a gear wheel.
Swipe until you find the iTunes Store and App Store.
At the top you will see your Apple ID in blue, click there.
A small screen will appear with several options, click Sign out.
Of course, you must remember your Apple ID and your password, because when you connect again it will ask you for it.
Reboot your device by holding down the Home and Start key and don't let go until the Apple apple appears. Don't be scared, at first the screen goes completely black, keep pressing the two keys, the Apple apple will come out.
Go back to the same place again, this time opening the session again and try to see if now you don't get the error.
In 99% of the cases, this method works, but if for one of those computer things you continue with the same error, leave your comment and we will try to help you.
