your link said,
https://www.youtube.com/watch?time_continue=637&v=4CbN_sgf_h8
I searched for it and got this link,://www.youtube.com/watch?v=4CbN_sgf_h8
I took out the HTTPS in mine or else the video comes up.
Your link says watch?time_continue=637& in it. That is what is making it not show.
All I did was search you tube, found the video and copy and pasted the link.
Don't use the you tube icon.
I don't know how the part in red above got into your link?
The time_continue didn't come up in my search.
Edit, the c in your link comes up as continue when you read the link in you tube, the one you posted.
