i signed out but cannot sign back in

Hello paa8291,

Thank you for using Apple Support Communities. You mentioned that you signed out of your device and you're unable to sign back in. If you're receiving an error message, we'd like to help troubleshoot it. Let's follow the steps below:

1.) Refresh things by restarting your iPhone: Restart your iPhone - Apple Support

2.) Make sure you're connected to a strong reliable Wi-Fi network. If you're already connected to a Wi-Fi network, try using your cellular network.

3.) Make sure you're not using any VPNs: Check VPN (Virtual Private Network) and third-party software to help resolve network connectivity issues - Apple Support

4.) Check to see if you have a configuration profile installed: Install or remove configuration profiles on iPhone - Apple Support

5.) If you're unable to sign in due to the sing in option being grayed out and not accessible, see if you have any restrictions enabled: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support

We hope these steps help you. Thank you for using Apple Support Communities. Take care.
