The videos used in the system are served from a separate location, outside of https://www.cacareerzone.org/. If you are connecting to the site through a firewall, you may need to ask your network administrator to grant access to a few additional sites.
Granting access to player.vimeo.com as well as *. vimeocdn.com will generally allow only specific videos to play. However, if you would also like to browse videos posted by other people on Vimeo.com, you will also need to allow *.vimeo.com.
