according to Steemit for security reasons not all iframes are supported. YouTube, Vimeo, and SoundCloud are the only supported servers. Here is a link: https://www.steem.center/index.php?title=Tips_for_formatting_your_post#Video_.26_Media
The only solution is to request a support ticket or get the two companies to agree on some security terms. I will update in the future.
