Video Not Appearing and Video Link Disappearing

Hi, I’m trying to embed a video onto my site, but whenever I paste the share link into the URL input, nothing shows up. When I go back to the video settings, the URL input is empty again as if I never entered it in the first place.

Any idea as to why this is happening and how I can get the video to work? Thank you!
