Can’t connect to App Store? Is the App Store not loading on your iPhone? Or are you trying and failing to download an app or an update to an app? This is quite a common problem and we recommend you work through the following steps to try and fix the problem.

1. Check if the App Store is down

It could be that the App Store is down - check the Apple System Stated page here.

2. Check your web connection

Make sure you are connected to the internet - visit google.com, for example. If it turns out you are having WiFi issues, here’s how to fix WiFi problems so you can get online if your WiFi network is at fault.

3. Try another WiFi network

Even if the WiFi network is working there may be some sort of restriction on it that is stopping you from accessing the App Store. Try using an alternative WiFi network or check the DNS settings of your WiFi network.

4. Check your DNS ports

It might be that your DNS server is set up incorrectly or that the server is set to block the App Store which connects using ports 80 and 443. This article explains how to check your DNS settings, although if you don’t know how to do this you probably don’t want to try it so move on to the next step!

5. Are you set to download over 3G or 4G?

Are you on a cellular connection but your phone is set to only download apps over WiFi? If your iPhone is set to only download apps over WiFi you won’t be able to download apps over a 3G/4G connection. Check Settings > Mobile Data and make sure the slider beside App Store is set to on (assuming you want to use the App Store over mobile - otherwise connect to WiFI and make sure your WiFi network is working, see above).

6. Have you run out of data?

It might also be the case that you can usually download apps over a cellular connection but that your data allowance for the month is maxed out. Alternatively it might be that the app in question can’t be downloaded over a mobile connection because it is really large and iOS stops you downloading really large apps over a data connection.

7. Try loging out and loging in again

Still not working? Try logging out and then log back into the App Store on your iPhone - that should fix it:
1. Go to Settings > iTunes & App Store
2. Tap on Apple ID and Sign Out
3. Log in again using your Apple ID and password

8. Clear your memory

Perhaps it’s a memory issue (older iPhones, especially those with less RAM and less storage are prone to this). Double tapping the Home button and swipe up on the App Store to close the app. Reopen it and see if that fixes the problem. If it doesn’t, close all open apps and turn your phone on and off again to clear the memory.

9. Force refresh the App Store

You could also try force refreshing the App Store app by tapping ten times on the App Store navigation bar (that’s the one at the bottom of the screen that is populated with Featured, Categories, Top Charts, Search and Updates). You should see the app flicker - this indicates it’s reloaded.

10. Check your data & time settings

Check that the Date & Time are set to automatically update (it seems that the App Store uses this, perhaps to check on your location). Go to Settings > General > Date & Time and choose Set Automatically (this setting means that if you travel from, say London to San Francisco, as soon as your iPhone recognises it is in a new territory it will automatically change the time accordingly.

11. Reset your network settings

Try resetting your network settings. Go to Settings > General > Reset > Reset Network Settings and see if that fixes the problem.

12. Update your software

It’s wise to make sure your software is up to date. Check Settings > General > Software Updates and check that there are no updates - sometimes there is a known issue that Apple may have fixed with a software update.

13. Is the app no longer supported?

It’s possible that you are trying to update an app that is out of date and no longer supported by iOS. In this case it may be that the update fails. Try downloading a different app.

14. Contact Apple

If all else fails you could contact Apple - here’s how to contact Apple support in the UK. http://www.apple.com/uk/contact/
