My javascript video player controls stops working when i use cloudflare

My site is a LMS, the video player controls like forward backward and speed controls stops working when i enable cloudflare on that.

Do anybody faced such issues? any solution?

What’s the URL of the page in question?

Hi

It is a demo of my original site for checking you can login via login page (https://pharmle.com/login)

Use these details to log in:
username: [email protected](dot)com
pwd: 123456

after that check these links:
