Fix “Failed to Verify Server Identity” Error on iPhone or iPad


The Mail app that comes with your iPhone or iPad is great for integrating your email accounts into a single app, that is, until it stops communicating with your mail server. Here are some potential fixes when Mail gives you a “Failed to verify server identity” message.

Change or reset your connection

The first thing to try is a different internet connection or resetting your connection. Although your device and the mail server may be working fine, it is possible that your local internet connection has developed a problem.

Most problems connecting to an Internet Service Provider (ISP) are resolved by logging out, waiting a few minutes, and then logging back in. Turn off your router and modem (if they are separate devices), wait about a minute, then turn everything back on. For a completely clean new slate, also consider resetting your network connection on the device.

kill the app

iOS and iPadOS are aggressive in keeping an app’s memory state in long-term storage. So it is quite possible that your Mail application has not been closed for months or even years.

Swipe up from the bottom of your screen until the app carousel appears. Swipe right until you find the messaging app, then swipe the app itself to kill it. Then open it again to see if that fixed the problem.

Restart your device

Restarting your device is a general troubleshooting tip, but something a surprising number of people forget to do when they’re having trouble with their technology.

If you’ve never turned off your iPhone or iPad, just hold the volume up and side button until you see “Slide to Power Off”, then move the slider until the device turns off. turn off. Then press and hold the side button to turn the device back on.

Check for iOS updates

The Mail app is a proprietary Apple app. So when you update iOS or iPadOS, you also get a new version of Mail and all the other iOS apps that come with it. If your server error is the result of an outdated app or a bug in iOS or the app, an update is a quick way to fix the problem.

To do this, see our guides for updating an iPhone and updating an iPad.

Check if the server is really down

An error that tells you that the server is not acting as it should may actually be the result of a server malfunction. The quickest way to check if the mail server is actually running or if it’s just you, use a site like DownDetector to see if the problematic account’s service provider is online or not.

Using DownDetector is relatively simple. All you have to do is type the name of your email provider in the site’s search bar and it will return a result telling you if other users are also complaining or can’t access their accounts.

If your email is provided by a private server, such as your company’s email server, you won’t find that information here. Instead, you’ll need to contact that mail server’s help desk or system administrator.

Disable SSL

Although we don’t recommend it in general, it seems that some users have managed to get rid of this error by disabling Secure Socket Layer (SSL) encryption for this account. However, if you do this, it means your emails can be intercepted and read, so be careful.

Open the Settings app and navigate to Mail > Accounts.

Delete account and re-add from scratch

If none of the above troubleshooting tips work, you can completely remove the email account from your device and then add it back.

Go to Settings > Mail > Accounts and select the problematic account. At the bottom of the account settings page, select “Delete account” and

Delete iOS Mail Account

Confirm it by selecting “Delete from my iPhone” or “iPad”.

Once the account is deleted, go to Settings > Mail > Accounts. Then tap “Add Account” and enter your account information as instructed.

If that doesn’t work, you may need to consider factory resetting your phone, but before you take such a drastic step, triple check your account details and check with your email provider to see if there are known issues.

You can also try a third-party messaging app! Microsoft’s Outlook app is a solid alternative to Mail, and you can even add non-Gmail accounts to the Gmail app.
