360 Error Viewing: "Error" "Error"

I recently upgraded from SL2 to 360. Most of the 360 courses will not play in our customer portal. Some play, most don't. The screen only says "Error" "Error". No problems with SL 2 or 3 projects, only some of the 360. I confirmed that I am publishing to "Web".

(No problems viewing any of these 360 courses in our LMS.)

Any ideas what could be causing this?
