Stream player controls not working in Wordpress

Hi I use the Guttenberg editor to ad blog posts and the site uses Cloudflare CDN. All the Stream player controls are no longer working. I cant click the full-screen button anymore or drag the progress bar to a different point in time or even volume. I use JS and CSS minify and I m not sure if that can cause an issue? Thanks for any help. Strange enough on the same site the player works very well on pages but not at all on blog posts.

Anyone having the same problem it was due to the comments overlapping the player so adding a spacer solved the issue
