Videos not working properly

I have encountered a problem where I can watch videos, but a lot of them display the “video is unaviable/blocked” no matter that I can play it with no issue on youtube; both with on and off vpn this issue is still persistent and won’t let me watch music playlist with friends and sometimes even normal videos definitely not blocked in my country. I don’t know if it’s a big or if I’m missing something, help would be greatly appreciated.

Thanks a lot for your feedback. Can you post an example video which is not working?
