Identity verification error “the identity of notiftoday.online cannot be verified” pop up on iPhone

You may have a subscribed Calendar or a CardDAV account for Contacts or Calendars.

What happens when you click the "Details" on the error popup message (See the Pic below)

Best would be to Delete and Add the email account that is creating the issue.

You may also try changing SSL settings

Settings > Password & Accounts > [Select the Mail account} > [Tape on Account with the email ID} > Advanced > SSL Settings > [Disable]

Click <Account (in Blue)

Click on DONE (in Blue) when exiting in the previous screen

If a Server Cannot be Identified:

Getting Around that:

In general, when you get this error, you may need to get a trust certificate. To do that, contact the site. Also, which protocol are you using for network security? WPA2 may do the job. Contact your network administrator, if this is not what you see. Also, disable all VPN connections.
