Gallery videos wont play

Hello,

I have a gallery embedded on one of my pages and it looks good with the video thumbnail visible, title of video and description. But, when you click on the play button nothing happen and the video doesn’t play. Is there something in the setting I need to activate or am I doing something wrong?

Any help would be appreciated, Thanks!
