iOS Safari "This Connection Is Not Private"

New Contributor III

We have a team of maintenance guys that logs in to a server console via Safari example: https://IP ADDRESS.

The issue that we are having is that they are met with a "This connection is not private." page and with no way to continue anyway or trust the cert. Now if they go to Chrome or Firefox app, it works just fine, but since this is used constantly I would like to make a webclip of it on the home page and that can only be done on Safari, from the looks of it.

I have also tried:
Downloading and uploading the cert into the config profile.
as well as white listing the URL within Content Filter.

Anyone else run in to something like this?
