But even after the SSL certificate was installed, the web page would have the error while FortiSASE applies with deep inspection as below:

It is because of security reasons, iOS will not trust the imported certificate by default. To trust the FortiSASE certificate:

 

  1. Search 'cert' in the Settings.
