YouTube video displays a gray thumbnail

Reviewed March 26, 2025

The Issue

gray generic video thumbnail image.

Video components display their YouTube video with gray generic thumbnail. This correlates with selecting the 'play in popup' setting.

Workaround

We are investigating a solution for this issue. YouTube appears to be trying to load a high resolution image that may not be present (maxresdefault.jpg). 

A quick workaround is to not use the 'play in popup' setting.  

A possible solution is to reupload the thumbnail image in YouTube and make sure they are set for the high resolution 1920px by 1080px.
