How to Fix Cannot Verify Server Identity on iOS: Easy Guide!

When doing work, like sending and receiving emails, iOS devices can get errors like “Cannot Verify Server Identity.” This happens when the device can’t check the mail server’s certificate to see if it is real. The verification process says it’s not real because the signature is wrong, the certificate has expired, or the server name doesn’t match the given domain name.

With this error, users can’t send emails to each other through the account, so it’s important to fix it quickly. Right now, you can use Norton’s LifeLock to keep your email account and other personal information safe.

How to Fix the Problem of “Cannot Verify Server Identity”

iPhone and iPad users have to do a few things on their devices to get rid of the error “Cannot Verify Server Identity.” Which one is perfect for you depends on why your iPhone or iPad is giving you an error. Here are the most common fixes to solve the problem.

Solution 1: Restart your iPhone or iPad.

Directly restarting the device is one of the easiest ways to fix the “Cannot Verify Server Identity” error. This easy way to fix a problem will mess up the server connection and make it start over when the computer reboots. Note that you can do this step even if you don’t know what caused the error. It’s a small failsafe step. If the problem is more complicated, the error message won’t show up right away.

To turn off the iPhone or iPad, hold down the Up volume button and the side button. Hold down the button until the “Slide to turn off” option shows up. Move the slider to the end, and the device will turn off. Then, tap and keep holding the side button until the device starts up again.

Solution 2: Get rid of the Mail app

Some iOS users leave the Mail app open all the time, which can slow it down or cause errors. So, to open the app carousel, you should swipe the iPhone screen up. Swipe right until you get to the Mail app, then swipe up on it. Turn off the app for now and turn it back on later.

Solution 3: Turn off and on your Internet connection.

Some people get the “Cannot Verify Server Identity” error on their iPhones or iPad even when the mail server and device are fine. This can occur if something goes wrong with their local network connection.

If your connection to an Internet service provider (ISP) is the problem, disconnect and reconnect after a few minutes. Also, if you are using a modem or router, you can turn them off. After one minute, start over again.

Solution 4: Check the update again for iOS

One of the apps that come with an iPhone or iPad is the Mail app. So, updating the iOS or iPadOS system to a new version can change the Mail app if software upgrades are included in the update. If you are using an older OS on the device and get the error “Cannot Verify Server Identity,” you should update the IOS.

Solution 5: Resetting the network settings is the fifth step.

As in Solution 3, you can disconnect and reconnect your internet connection, but if the problem still happens, it’s better to reset the network settings. When a user resets the network settings, the process deletes all of the most recent settings, such as any changes the user made to the settings. It will put things back to how they were before and fix the problems that caused the verification problem.

How do I do it?

Solution 9: Make sure your iOS carrier settings are up to date.

If an iPhone is working with an out-of-date carrier setting, the verification problem is stopped because the two things don’t work together. Plus, your accounts won’t be able to connect correctly if your iOS carrier settings are out of date. To remove the error, you should change these settings.

How do I do it?

  1. Start by opening your iPad or iPhone and going to Settings.

Solution 10: Fix the small problems.

There are some other things that can cause the “Cannot Verify Server Identity” error prompt on an iPhone or iPad. For example, if the server name and domain name don’t match up, the verification process will see the certificate as wrong or fake. You can fix the problems with the domain name and server name by taking a few small troubleshooting steps.

People who use a Shared Hosting connection can get rid of the problem by changing the mail server settings on their iPhones.

Changing the server name for the email to match the name on the certificate will work for hosting customers with VPS accounts. VPS users who are using a self-signed certificate may run into this problem, but that is not considered to be their fault. You should get a certificate of responsibility from a source that has been registered.


Depending on what caused the error, you can try different things like restarting the app or device, resetting connections, or removing the account and adding it again. After you try these things, see if the steady mail process is working again. Use the trusted Norton LifeLock software to keep your account information safe while you try out these solutions.
