YouTube Videos Not Playing

I’ve used the Video component successfully in the past, but for some reason it isn’t working for me today on a new project. Clicking on the video in the browser preview does not play it - it simply vanishes from the page. Can anybody help?

Project uploaded here :elementsapp://downloadDocument/cyBc6Hvwp4eU

you havent dragged the video into the video box from your resources!! its empty…looks to me like youve dragged it into the thumbnail box. they also wont play unless published. you will get video unavailable in preview

thanks…your welcome

I have a similar problem but I have the video in the video resource and it has worked before but now doesn’t (don’t know if video component was updated or my host is screwing up). I would prefer to have Vimeo host the videos but I’m not sure how to do this: modal? Html?

Regardless, if you go to Bailin.works/presentation and click on either video thumbnails, nothing appears in the video. This happens throughout the website with video.

In Browser video with play button:

Browser after clicking on video play button:

Note: This website is locked except for the presentation page which is accessible.

it works fine in preview…

Video works on Chrome but not DuckDuckGo or Safari. Anyone know why that would happen?

Still need an answer. Why is my video not functioning in Safari or DuckDuckGo Browsers? Is there a code or setting I need to add to the video setting? All other browsers function.

I see that I get this error on Safari:

How do I solve this?
