I'm having the same issue. Apparently they've been having issues for a long time and it sounds like the owner abandoned the site. I can view the first few seconds of videos, but that's about it... trying to download them they get stuck then eventually fail.
I did find a way to fix the layout of galleries tho with Chrome DevTools. While on the Cyberdrop page press Ctrl + Shift + i > Sources > Snippets and use the following code to convert the cyberdrop.me to Cyberdrop.me
document.body.innerHTML = document.body.innerHTML.replace(/cyberdrop.me/g, "cyberdrop.me")
document.head.innerHTML = document.head.innerHTML.replace(/cyberdrop.me/g, "cyberdrop.me")
