youtube video not avialable

Hi, I am developing on site being accessed via IP address. When I add a sermon video link from youtube, then go to the front end page to show the sermon, I see the image with the Play button, but when i click play, it shows “video not available”. Playing it right in Youtube works fine, so i know it is there. Also, setting up the sermon video on another site running Sermon Manager works fine. The only difference I can see is the URL of his site is a legit HTTPS, not just a straight IP address (which is HTTP). Could that be the problem?

thanks for any advice!
