This issue has troubled many iDevice users, so here are the best solutions I’ve seen – each of these has proven successful for many users:
DNS Settings Change
This fix has been recommended by Apple support and has proven successful for many commenters on my previous post. The way this works is to change DNS settings on your iPad or whichever iOS device is affected – by adding Google’s DNS server/s. Here’s how to do this:
– Go to the Settings app and tap on the Wi-Fi section in the left sidebar
– Then look at the ‘Choose a Network’ section in the main right-hand side area of the page and look for the network name that has a check mark next to it and rendered in blue text – the WiFi network you are currently using
– Tap on the blue arrow at the right-hand side of the listing for that network.
– On the next screen you’ll see a section labeled ‘IP Address’ with three large buttons below it. Make sure the DHCP button is selected. Below that you’ll see fields for IP Address, Subnet Mask, and others. Tap on the DNS field (the fourth one down).
– This will bring up the iDevice’s on-screen keyboard and place the cursor at the end of the IP address for the DNS server currently being used by the iDevice. Backspace until all the numbers for that address are gone. Then type this in:
Please note the periods after the first three 8s. You can also use 18.104.22.168 – both are valid addresses for Google’s DNS servers.
Download an App Via the Purchased Tab in the App Store
– Open the App Store app on your iDevice.
– Tap on the Purchased button in the bottom navigation bar.
– This will show you all the apps you’ve purchased on the iDevice. Those that are already installed with a greyed out label. Others will display a small download icon, showing a cloud with a downward facing arrow in it.
– Tap on one of the download icons and download a purchased app.
For many users this has cleared some sort of App Store queue and allowed them to resume with normal updates. Some have had to repeat the download with a few apps in the Purchased section.
Set the Date Forward and Revert Back
– Open the Settings app and go to General > Date & Time
– On the Date & Time screen, tap to turn off ‘Set Automatically’
– Tap on ‘Set Date & Time’ and enter a date a couple of years or more in the future.
– Go out of Settings and then straight back in and turn ‘Set Automatically’ to restore the current date and time.
One of these methods should get you past the Cannot connect to iTunes Store errors and allow you to install new apps and do app updates without further problems.
Let us know which method worked best for you and if even after trying the aforementioned solutions, you are still faced with this issue. Cheers!
