How to fix “cannot verify server identity” error

“Cannot Verify Server Identity” is a common error in iPhone and other iOS devices. Below we will cover how to fix this error on your iPhone / iPad.



What is the error Cannot Verify Server Identity?

When an iPhone tries to connect to a mail server securely, it’ll fetch the server’s “SSL certificate” and check if it is reliable.

If it finds the certificate changed, or not matching the domain name, or not signed by a well-known company, it’ll mark the cert as unreliable.

At that point, the secure connection fails, and iPhone or the device will show the error “Cannot Verify Server Identity“.

Unfortunately, the error can appear when using 1-grid mail servers. It even pops up with popular mail servers like eas.outlook.com, imap.gmail.com, etc. too. 


Solution:- Changing your Mail Server Name

Many hosting companies provide the mail server name as “mail.website-name.com”. Whereas, the certificate of the mail server will be in the format “mail.server-name.com”. When configuring iPhone users put in their mail server as “mail.website-name.com”, but when iPhone fetches the certificate, it sees the name “mail.server-name.com” printed in it. iPhone plays it safe and marks the certificate as unreliable. Below we will cover how to update the hostname to your mail server name.
