If you can't connect to the App Store, iTunes Store
To fix the issue, check your settings and network connections on your iPhone, iPad, iPod touch, Mac, PC, or Apple TV.
When you try to open the iTunes Store, App Store, or the Book Store in Apple Books, you might see a "Cannot connect to iTunes Store" alert message or something similar. The iTunes Store, App Store, or Book Store might also not load anything at all, or might unexpectedly stop in the middle of downloading content.
If you have a separate issue where iTunes doesn’t recognize your iPhone, iPad, or iPod touch when you connect the device to your computer using a USB cable, get help.
Store availability and features might vary by country or region. Learn more about what's available in your country or region.
Check your connection
Make sure that your device is connected to the Internet. Try using an Internet browser to connect to any website and see if it loads. If it doesn't, use another device on the same network to see if it can connect to any website. If no other devices can access the Internet, turn your Wi-Fi router off and then on again to reset it. If you still can’t connect to your Wi-Fi network, contact your Internet provider for more help. If only your first device can’t connect to the Internet, get help with Wi-Fi on your iPhone, iPad, or iPod touch.
If you use cellular service to connect to the Internet on your iPhone or iPad, make sure that you have cellular data turned on for the iTunes Store, App Store, and Apple Books: Go to Settings > Cellular, and turn on Cellular Data.
Check System Status
Visit the Apple System Status page to see if there are interruptions in service in your country or region.
Update your account
If you're not able to access the iTunes Store, App Store, or Book Store because you can't log in with your Apple ID, learn how to reset your Apple ID password. If you recently changed your Apple ID or password, you might have to sign out and sign back in. To sign in on your iOS device, go to Settings > [your photo] > iTunes & App Store. Tap your Apple ID, sign out, then tap Sign In to log in again. Learn how to sign out on your Mac, PC, or Apple TV.
If you're asked to verify your payment information, make sure that your payment method, first and last name, and billing address are correct and exactly match what's on file with your financial institution.
Update your software
Update to the latest versions of iOS, macOS, tvOS, iTunes, or your PC's operating system. Then try to connect to the iTunes Store, App Store, or Book Store again.
Check the date and time
Make sure that the date and time on your device are set correctly for your time zone.
On your iPhone, iPad, iPod touch: Go to Settings > General > Date & Time. Get more help with date and time.
On your Mac: Open System Preferences > Date & Time.
On your Apple TV: Go to Settings > General > Date and Time.
On your PC: Search for timedate.cpl using the search box or Search charm.
If they're not, set the correct date and time, or turn on the option to set it automatically.
On your iPhone, iPad, or iPod touch
