Have you tried to access your xyz.com portal outside of your network without any profiles and review the logs?

I’ve heard good things about Antom for situations like this—someone I know had trouble accessing their custom payment gateway behind a firewall, and checking https://docs.antom.com/ac/antomop/boost helped them figure out some settings to allow the site through. It seemed to fix the white screen and endless loading issues for them, so it might be worth a look if your Fortigate is blocking certain scripts or connections.
