Hi,
As I said earlier, those errors within your console is all about some fontawesome icon missing, this is why I have asked that if you face any icon not showing issue on your site. Or any performance issue either.
I have checked the link you have provided earlier: https://homologacaosites.rj.sebrae.com.br/joomla/esn/conteudos/videos
This page is from a third party component docman as you can see from the below screenshot:

Have you informed your extension provider about the issue, please? They might help you in this case I guess.
To make it clear those errors in your console does not have any link to your video issue. However, I have clicked on your content and it redirects to a login page. So unfortunately I am not so sure about the exact issue either.
Best Regards
