Description

This is a paid Udemy course that I own. The course link I used was the share link. The videos play fine in my web browser. Thanks fellas! The number of videos seems correct for this course (369). I have a feeling that Udemy is somehow detecting the download attempt. I've looked at the other issues regarding Udemy, but they all seem to at lease be able to download the first few videos.

I'm also receiving 403 errors using the same command. Attached is the verbose log.

I read through the other Udemy issues closer and this looks like the same issue as the others, so I'm going to close this issue and link to the other issue: #22162
