Hi, I'm having issues playing videos on Udemy, the video won't start. It works fine on Firefox and Chrome.

If I open the Opera DevTools I can find there is an error:

VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) No compatible source was found for this media.

And the stacktrace:
At
code: 4
message: "No compatible source was found for this media."
responseContentType: "application/x-mpegURL"
responseStatus: 200
responseUrl: undefined
proto: Object

I also found this old thread, but no solution was provided.
