Description

All courses from https://unf-vault.teachable.com/ are now producing the above error, 2-4 weeks ago these were working just fine. I have updated my cookies file today incase that was a problem.

There are other issues with Teachable reported, but none of them reference a 'Unable to find video URL' error.

Probably the expected page for video 38493768 was redirected to a captcha or login page.

Please use --write-pages and attach the saved page(s) corresponding to the id 38493768 in the log.

@dirkf 38493768_https_-_unf-vault.teachable.com_courses_1696460_lectures_38493768.log

I renamed the .dump as .log due to git's upload restrictions.

I also have the same issue. Could I be notified when this gets fixed?

So the page posted by @CanisHelix looks like a proper video page.

But the extractor is looking for a Wistia video ID, either in an actual URL like https://wistia.com/embed/.../ID or in a CSS class name wistia_async_ID of a div element, or as the value of some id or data-wistia-id HTML attribute, or as the parameter of the JS function Wistia.embed(), or as the value wistia_ID of some id HTML attribute (phew). None of these is found.

We do however have:

<div class='hotmart_video_player' data-attachment-id='70094420' data-course-id='1696460' data-lecture-id='38493768' data-user-id=...>

Hotmart doesn't have an extractor yet, and may be challenging: see #30971.

In summary the site has changed its video hoster, or added a new one, and affected pages won't work for the moment.

Could I be notified when this gets fixed?
