One of the common issues which are faced by users of iOS devices is problems relating to cannot verify server identity. This issue is faced when the device considers the server certificate of mail fake.
When an iPhone tries to establish a connection to a mail server it would fetch all the details relating to the server’s SSL certificate and would automatically check reliability.
It is marked unreliable if it fails to match the name of the domain, expiry of the certificate, or if it is not signed by a reputable company. This eventually fails to secure the connection and your device would show “Cannot Verify Server Identity.”

What are the possible causes of cannot verify server identity error?
Most of the possible causes when the certification is classified as wrong expired as well as it’s in the wrong domain. But there are also cases where the certificates are valid and also misclassified as fake by iOS devices.
Some of the possible reasons are as follows:-
#1. A mismatch between the server’s name and the domain’s name
Most of the hosting companies offer the server name of the mail as “mail.website-name.com.” The format of the mail server certificate would be like “mail.server-name.com”.
During configuration of iPhone users name the server of the mail as “mail.website-name.com”, after the certificate is fetched by iPhone the name which is printed on it is “mail.server-name.com.” iPhone tries to play sage by marking the certificate as unreliable.
#2. Bug in iPhone and iOS devices
Apple devices use very strong verified checks for assurance of security of the certificate. At times when there is no possible way for changing the name of the certificate servers or the mail user’s MX name then the respective error cannot be removed.
In some cases this error crops up when the certificate of the server is changed, then it is suggested to the mail users for adding the SSL certification of the server to the ‘Trusted list.’
You just have to click the ‘details’ button which is written in the error message. And tap on the ‘Trust’ link which is present on the next screen.
#3. When the server certificate of the mail is changed.
#4. During the setup of a new account in iPhone or during the migration of an account.
#5. The error can also crop up while you are using any mail servers. The pop-ups can also come with mail servers such as eas.outlook.com and imap.gmail.com
How to fix this issue?
Some of the ways to fix this issue are as follows:-
#1. Change the name of the mail server
Most of the time when the hosting customer constitutes a VPS account, the name of the mail server is changed to match the name of the certificate.
#2. Fixing configuration of the mail
In this case when the hosting user is also a shared hosting customer then they are helped to change the mail server settings of iPhone for using “mail.server-name.com” in place of “mail.website-name.com”.
#3. Setting up a free dedicated certificate
The users of VPS who don’t have a valid certificate, their certificates are set up by them which is valid.
