Tumblr video downloads

Hi everyone, I recently tried to download a video from tumblr on google chrome using my usual Right click----->click Inspect---------->click networks tab-------> and search for the mp4 file

Today when I tried this method on multiple different videos there was no mp4 file also got a lot of "failed to load resource" messages on the bottom of page. I was wondering if anyone else was having a problem downloading videos from tumblr. And of course any solutions would be greatly appreciated thanks
