O'Reilly Access (not unlimited?)

[jdessino]

I didn't see anything as to whether this was happening when accessing via Primo, the O'Reilly platform, or both, so I decided to try it both ways. When I went directly to the O'Reilly platform, I was able to view videos without any error message. And I made sure to let the video run for a few minutes. When I tried to access the same video (Python Programming by Mike McMillan) through Primo, I got the 403 error. Since the error occurred on the O'Reilly site, I went up to the O'Reilly search box and searched for the video and was able to watch it with no problem.

Emily: does this O'Reilly authentication issue occur only under certain circumstances, or only intermittently, or was I just lucky?
