@jonreese this sounds like it may have been a timeout error with Embedly (the provider we use for the video integration). When I tested with your video on my end it worked without any issues?
I’ve also had this happen to me once before when the video was freshly uploaded: Webflow - videorz
Thanks @waldo! I’d never seen that error before. I had already tried refreshing the Designer which didn’t work, but restarting my Mac for some reason did. Anyhoo, works now. Thanks!
