If you have a VPN App or profiles installed, or a security/AV/firewall App such as Norton, these may be interfering with your iPad's network connection. If applicable, the resolution is usually simple; you may need to temporarily disable or remove the Security App and/or VPN.
After the offending item has been removed, you may need to perform a forced-restart of your iPad:
Force restart iPad (models with Face ID or with Touch ID in the top button)
If your iPad doesn’t have the Home button, do the following:
- Press and quickly release the volume button nearest to the top button.
- Press and quickly release the volume button farthest from the top button.
- Press and hold the top button.
- When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)
Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
