The attendee test page is to verify all features within the virtual conference will work on your computer. The page includes a feature sample (left) and an expected sample image (right). If the featured sample doesn’t show up and all you see is the image, you will experience the same issues once logged in. This may be due to a firewall block or restrictions set by your VPN. If this is the case, supply your IT department with this page so they can remove any restrictions. A list of site sources can be found under the red “X” below.
