I understand there was a fix recently to the safari extractor with changes to the way the kaltura session is handled. This seems to have fixed the problem for some videos but not for others.

I have included debug output above for a working video course and one that isn't. I don't know if useful at all but using chrome developer tools I have logged the network for each of the courses for one video and exported as a HAR file, please see attached google drive link.

You must use credentials.

You must use credentials.

I have tried with credentials with the same result. I will try again just to double confirm though

EDIT: Well i'll be damned it's somehow working now. Apologies for the invalid issue.
