The log file you sent is a bit hard to read in a Word doc, so it might be best if I can generate my own to look at.
Can you please supply me with a URL link to the video/site so that I can test it?
If it requires login credentials can you please send them privately to firstname.lastname@example.org, so long as you are comfortable with it.
The actual video file does not download from the browser or by direct URL. In some cases, Jaksta downloads hundreds of files from the single webpage/URL.
