A course video will not play

Course videos play in a protected player that works only on progsity.io, for a signed-in student who has the course. Most problems go away with one of these:

1. Reload the lesson page. Each video link is signed for a few hours, so a lesson tab left open for a long time can stop playing.
2. Check that you are signed in with the account that has the course.
3. If you opened the link from inside Facebook or Messenger, open the page in Chrome or another browser instead.
4. Try another browser, and turn off extensions that block content on the page.
5. Check your internet connection. A slow connection can keep a video loading for a long time.

Still not playing? Open a ticket in Course access with the course, the lesson, your device and browser, and a screenshot of what you see.
