Unable to watch any course video

I'm at: "https://role.rhu.redhat.com/rol-rhu", I launch the "CL110: Red Hat OpenStack Administration I" course, select Video Classroom Launch and receive the message: "Error Loading Player: No playable sources found". I've attempted this with several other courses and received the same result.

My OS is Fedora 28, updates are current.

How can I download and/or watch the video portions of the course?

Thank you.
