My site crash when i embed multiple videos

Hello!

I am creating a page with many videos on modals, but when i try to open the page on front end, it never loads (On mobile it shows “too many requests” error).

Is there any way to solve it? I tried many methods, even the Labnol method but it doesn’t work properly with modals (Method: https://www.labnol.org/internet/light-youtube-embeds/27941).

Thank you
