If you installed a profile comprising a certificate payload in iPadOS or iOS, the certificate isn’t entrusted for SSL. You’ll need to manually enable trust for SSL/TLS whenever you install a profile received or downloaded from the web. To turn on SSL/TLS trust for a certificate, follow these steps: 1. Launch the “Settings” app. 2. Navigate to “General,” “About,” then “Certificate Trust Settings.” 3. Beneath “Enable full trust for root certificates” activate trust for that certificate. Apple advises using Apple Configurator or Mobile Device Management (MDM) to deploy certificates. The certificate payload will be automatically entrusted for SSL if installed using Configurator or MDM or to form an MDM enrollment profile.
