It is not possible to connect to App Store

Hello gabi216,

I believe the real problem for you is that you cannot update the iPad. I am not aware of any iPads so old they cannot update due to hardware issues but I could be wrong. This article has steps to update when issues or errors pop up.

If your iPhone, iPad or iPod touch won’t update - Apple Support

If still not successful I would reach out to Apple Support about the inability to update. Get Support

It seems you have already read this and I agree the iOS version is likely the issue. Incase not here it is.

If you can't connect to the App Store, iTunes Store, or other Apple services - Apple Support

I hope this is helpful,

First, try signing out of the app store, restarting, and signing back in again. Link > Restart your iPhone - Apple Support

Then failing that… Here’s a troubleshooting sequence > https://www.payetteforward.com/iphone-cannot-connect-to-app-store-real-fix/

Failing that, try backing up and resetting and re-installing iOS, using a Mac or Windows computer.

Failing all that, check with Apple Support using the Get Support link in the upper right.

Once (re)connected… Your iPad is also going to be too old for pretty much any available app, unfortunately.

Sorry, I don’t know how I missed that you had already replied.
