Alert symbol (exclamation point) when video doesn't play

Hello!

I have three projects that are similar, the only difference are the video links that they have. Two work fine, but two are not playing. I am getting an exclamation point, and I don’t know why. I changed what should be changed, but somehow it isn’t playing. Any help would be great. Thank you.

Hi Matt,

I’ve received your support ticket and have responded through there.

Thanks,
