Fix Cannot Verify Server Identity Error on iPhone & iPad

Can’t send or receive emails on your iPhone or iPad because the Mail app keeps flashing the message “Cannot Verify Server Identity”? Is this something you’re experiencing? This is most likely due to the fact that the Mail app is unable to interact securely with the email provider’s server. For example, if the email provider’s Secure Socket Layer (SSL) certificate is expired or untrustworthy, you’ll see this error message indicating so.

The Mail app may also show this error as a result of other circumstances such as software faults, a bad network connection, a server outage, or a short system problem. We’ll show you several ways that have been successful in resolving the problem for users who have had difficulties. Additionally, we’ll highlight some helpful methods that we’ve uncovered via our own research and experimenting.

First and foremost, be certain that you have an active internet connection. Check to see whether you can visit any webpages by opening your web browser. This will assist you in determining whether or not your internet connection is functioning properly. If your internet connection is not the source of the issue, one of the options indicated below should do the trick.

Close and Reopen the Mail App

Using your finger, swipe up from the bottom of your screen to see the iOS App Switcher menu. App Switcher may be accessed by double-clicking the physical home button on iPhones and iPads with a physical home button, as seen below. After then, slide up on the Mail app until it is no longer visible on the screen.

If the problem continues to appear when you reopen the Mail application, try the troubleshooting techniques listed below.

Switch to Cellular Connectivity

According to some iPhone users in this Apple Discussion thread, the error message only pops up when accessing mail via Wi-Fi. Surprisingly, switching to cellular or mobile data resolved the problem. If you keep getting the “Cannot Verify Server Identity” error on a Wi-Fi connection, switch to cellular data and reopen the Mail app.

Restart Your iPhone or iPad

Temporary bugs that prevent the Mail app from detecting your email server may be fixed by restarting your device.

  • Select Shut Down and then select the “slide to power off” option.

Your gadget should shut down in roughly 10-20 seconds. To restart, press and hold the side button for a few seconds. Check whether you can send and receive emails without getting an error message by turning on cellular data or joining a Wi-Fi network.

Check Email Provider Status

The Mail app might fail to verify the account’s identity if the email client servers are experiencing downtime. Use third-party outage monitoring tools like DownDetector to confirm the status of your email provider’s servers.

For example, if the email is from a Gmail account, put “gmail” in the search field at DownDetector. The server status for Outlook and Yahoo! Mail may be found by typing “outlook” or “yahoo mail” into the search box.

Incoming emails to that address will no longer be encrypted using SSL. It’s worth noting that removing this option would make receiving emails less secure, even if this fixes the issue.

Upgrade or Update iOS

It’s possible that the “Cannot Verify Server Identity” problem is caused by a bug in your iOS build or inside the Mail app if you haven’t updated your device in a long time.

Connection to a Wi-Fi network is required. To download and install software updates, navigate to Settings > General > Software Update, then tap on “Download and Install.”

Installing an operating system update will also install the most recent version of the Mail application on your device.
