Thank you Wendy for the reply.Yes i have double checked the links on
preview the video plays.On publication when i play the story html it still
plays video but on uploading package to the scorm cloud i get a white
screen.
I am trying to think in line of browser but still that cant explain the
disparity.

Make sure that the links to your videos start with https (not http).

perfect hadn't tried that.Thanks alot mate.

Hi Dennis!

Looks like you were able to get the assistance that you needed here. Just let us know if we can further assist or if we need to take a look at your .story file.

After trying many things I think I found a solution that may help someone
out there:
1.If the video is embedded on a layer avoid using states on the trigger
buttons(somehow it worked)
2.The video as from youtube link copied reads https://youtu.be/kOkQ4T5WO9E
When I added embed code https://youtu.be/embed/kOkQ4T5WO9E?rel=0 it
displayed a security message but this solved the issue

Thanks for the help guys.

Thanks for popping back in to share Dennis :)

The key thing for me to get my videos to work in both chrome and firefox was changing the http: to https: as suggested by Michael.  

Is it possible to update the storyline help page here:  https://articulate.com/support/article/how-to-add-a-youtube-video-sl2

All the examples on that page currently give the http: url ?

Glad you were able to find the assistance that you needed here as well Lucy. Thanks for popping in to share and that is a great suggestion that I will share with the team.
