Website loading properly in Firefox, but not Chrome

[type or paste code here](https://www.omarimc.com/promotion/#op3-element-ftIekL4x)

Go to this link in Chrome and you will see that there are error messages for 3 video embeds on the page. Or if you go to [Preformatted text](https://www.omarimc.com/call/), there is a calendly embed that is not working.

I have already gone into Cloudflare and made sure this setting was on, “Automatic HTTPS Rewrites
Automatic HTTPS Rewrites helps fix mixed content by changing “http” to “https” for all resources or links on your web site that can be served with HTTPS.”

In Firefox, if you go to these same pages, you will not see an error message when viewing the embeds.

This just started happening late last week and this issue has never happened before. Any help?
