Errors using Download to/folder sync plugin

[goin3d 4]

I have a number of STRM files that I’ve been using the folder sync plugin to download local copies of.  Recently on a couple different machines every download is erroring out.  If I take the same URL and paste it into a browser window things download without issue.  In the log I see:

is this reading like something ffmpeg related?  I’m having trouble determining where to start tracking this one down.  I’ve also tried with the latest beta and receive the same result.  Appreciate any thoughts folks have!

Hi, a likely cause of this is that the site hosting the video is sending back incorrect http response headers. For example, the headers might say the content length is one thing, but then the actual content is shorter or longer than that.

Thanks!  I’m assuming there’s nothing I can do to compensate for that/copy the media anyway?

Can you use a browser debugger to confirm?

In a browser window everything comes down ok when I just paste the link in and download.  Given that would I actually see anything in the debug?  Apologies, I don’t do much in the browser debugger.

@goin3din the network tab of the browser debug console you'll be able to see the response headers sent back by the remote server. Can you get those?

In other words, try putting that somesite url into the browser address bar, and then looking in the browser debug console. Thanks !
