Downloadingh different video from FB few minutes ago works, the video plays in browser.

I got the same error with this video:

https://www.facebook.com/DavidCooper97/videos/10204648361313294/

However I was able to download another Facebook video so its not all that are dead.

When running OP's command, I received the same result: HTTP 500. But, when logging in to Facebook with -u and -p flags, that video was downloaded normally.

(On another note, that specific video description is not in my language, so the "See Translation" link was added to the description... and the filename as a result! "Máte ještě někdo neřešitelný problém See Translation-10205466528528287.mp4")

Loading up the original FB url in a Chrome incognito window gives me a 500 error most of the time. Eventually it does load after hitting it enough times.

Thanks @Adastras. For https://www.facebook.com/axel.klos.7/videos/1636612619944995/ (reported in #8578), both Firefox and Chrome on Linux leads to frequent HTTP 500 errors. I can't simply change the user-agent to a different one because Facebook serves more formats to Chrome. (See #8222 and #8374) Can anyone found an user-agent that reports DASH formats while not causing frequent HTTP 500 errors? By changing the following line in youtube_dl/extractor/facebook.py:

_CHROME_USER_AGENT = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.97 Safari/537.36'

And then run the following command:

$ youtube-dl -vF "https://www.facebook.com/video.php?v=957955867617029"

All videos mentioned here are working again. Seems Facebook has fixed their HTTP 500 errors. Feel free to open new issues if there are still problems.
