Have been using the Vimeo slide video for a long time, and it has been working well until now. Quite often I have had to insert the video twice before it works, but now I’m not able to insert it at all.
I have a Vimeo Pro account, and the video is set to “Unlisted”. I have tried  several privacy settings in Vimeo, but the result is the same. I have also tried to publish the video with Vimeo recomended settings from Adobe Premier, but it still does not work.

When inserting the video it shows “Loading video….” message with 50%…..and nothing happens.

Inserting a video from Youtube, and inserting it as a local file is working.
