I literally cannot get any other assistance for this error when I try and Google for it. It appears nobody has had it before. I start up my surface hub, it is domain-joined so I can login with a domain account on o365 and it syncs my calendar. However, when I launch Teams it consistently shows the bellow error. The Hub is up to date in terms of Quality and Feature updates. I have also tried uninstalling teams and reinstalling it, to no avail. The internet is working over the WiFi as I can launch Edge and browse around. I am out of options as to what else to try. Any thoughts?
