Typekit CSS 404 Error causing course not to load?

Hi All!

I have an elearning course generated by a 3rd party developer using captivate.  The course stopped playing on anything about 4 days ago.

Looking at some of the underlying errors, it seems it is with 404 errors tied to this url, which I think is maybe an adobe font?  https://use.typekit.net/.css?v=1745173564

I don’t have access to the source files but wondering if this is something anyone has encountered?

Thanks,

Susan
