I have a issue I hope someone here can assist me with!
My customer uses FortiClientVPN on +40 Windows clients, using SSO/SAML to connect to a FortiGate 1500D through O365 Azure - and it works flawlessly. 1500D firmware is v6.4.7,build1911,210825 (GA).
The customer has a number of Apple iPads, where I have been trying to get the FortiClient VPN app to work. But when connecting the logon page to O365 is just blank, it never loads the webpage. The settings are exactly the same as the Windows clients. I have tried with iOS devices that run version 15.2.1 and 12.5.5. There result is also the same if I use a trial for the "FortiClient" paid app.
I thought maybe it's a browser issue, so I tried changing the default browser on the iOS devices to both Chrome and Firefox, but nothing changed. I'm not sure if the FortiVPN app even registers the change.
See the screenshot below showing what I mean with the "blank page".
Just trying to bubble this to the top. I was having the same issue with one user on an iPhone 11. My iPhone 13 works fine. Hoping someone has a fix. It seems like the Office365 login page just isn't rendering in the browser that pops up. All you see is the CANCEL button at the top.
