@oskar,
I have re-typed your video URL into the test version of the plugin and checked the logs/errors of the browser console. Please take a look at the issue, which has caused the error.
Firefox:
Chrome:
Referring to the error message, it means that it is not possible to play your video, because of the service restrictions.
You can also check the reference, concerning the CORS policy:
The available solution in your situation - to upload the video file on another service and get its direct link (.mp4). For example, Amazon AWS.
Apologies for the inconvenience. Could you check and confirm?

Regards
