URL expires after few hours

[gongl]

The ViewPoints.ThumbnailUrl expires after few hours I clicked on "Refresh". The small thumbnails only show up for few hours and then they disappear. Then I have to refresh the page to make them show up again. See screenshot below. Is there a way to keep the thumbnails stay longer or never expire? 

Thanks!

Hi @gongl ,

If I understand your scenario correctly that your image urls work fine at first but they will expire after few hours?

If it is, what kind of your image URL? Where it is from?

In addition, what version of your Power BI desktop?
