PBI Dashboard Blocking Scripts or Cookies with iframe

I'm using the html viewer plugin to embed an iframe from Sketchfab. This used to work perfectly - the iframe from scketchfab would pull in a 3d model with no problems. However, this recently stopped working. Now, I get the following error where the iframe is: "It looks like your browser or this site is blocking some scripts or cookies necessary to properly display the viewer."

Any ideas on how to fix this? Or any ideas on another way to pull in a 3d model from sketchfab?
