Hello Sherlock820,
Welcome to the Apple Support Community!
Try following these steps to help resolve your problem:
- Take a look at Apple’s System Status to ensure Apple Servers aren’t experiencing any issues
- Check that you’re connected to WiFi
- Try using a different WiFi network or switch to your cellular data network (and temporarily turn off WiFi)
- If using a public WiFi network or a WiFi network that’s limited or restricted like at your workplace, try using Cellular Data instead or use a personal hotspot
- If you own another Apple device like an iPad, iPod, or Mac, generate a verification code on that device to enter into the other device
- Use one Apple ID for all Apple Services or toggle off any services (like FaceTime, Game Center, and Messages App) that use a different Apple ID
- Set your Date & Time to Set Automatically
- Restart or force restart your iDevice
- Try logging out of your Apple ID and then logging back in
- Sign out of the Apple ID in Settings >iTunes & App Store, wait 30 seconds, and sign back in
- Go to Apple ID’s website and reset your Apple ID account password and try with this updated password
- Turn off any advertising (adblocker) or Content Blockers
- Temporarily disable any VPN
Let me know if you need anymore help :)
Thanks, EpicX
