Hi Bogdan,
Seems my connection (wi-fi at home) works fine, I also try to use cellular date and it still get the same result. I also try to use another browser (opera and edge) and still can't play the video.
I was wondering that this happen due to the difference region. Because my friend (we're from Indonesia btw) also have the same problem. Just my random guess..
But thanks for try to solve my problem
Regards,
Stephen
