Hi Steven,

I assume you have an external server that you have defined in the Show and share config to store the published videos, correct?

When you upload the video on the Show and Share and try a preview, the video would be playing from the Show and Share device itself. When you publish the video, it is then deployed to the external server you have defined (unless you selected the "publish locally" option). At that point, when you try to play the video, it will be accessed using the base URL for the external server you have defined in your Show and share config.

I would double check if the extenal server location and base URLs used to reach it haven't changed after you had set it up.

Regards,

Marco
