I am trying to set up my Vive cosmos, when I launch the VivePort desktop app and login in it gives me an internet error and says to try checking my connections. I am running a Dell OptiPlex 5090, specifically ordered for my classroom for the VR system and CAD. This is the only app I have installed so far on this device. I use the computer daily to display for my lessons and the internet works just fine (ethernet). I asked the IT department to "open" Vive through the content blocker, and still no luck.
