That’s the case with an alert that can appear when an app or the operating system “Cannot Verify Server Identity” in iOS or iPadOS or “can’t verify the identity of the server” in macOS.

To correct the cannot verify server identity error, the first thing you should do is check that your iPhone is displaying the correct time and date and force quit the Mail application on your phone.

If Remote Desktop cannot verify the identity of the remote computer, check the time or date difference and then follow the solutions mentioned in this post to resolve the issue.

While browsing using mobile safari (latest version of iOS) I keep getting constant popups 'cannot verify server identity'.
