Frame-ancestors problem with embed twitch iframe

I am trying to use the twitch embed iframe on my website. It worked on localhost but when I put the website online and after changing the parent parameter to my website domain I get following error: Refused to frame ‘’ because an ancestor violates the following Content Security Policy directive: “frame-ancestors”.

My iframe in the html looks like this:

My website URL is:

If I open the Twitch in my browser by itself it works.


I use a no-ip free dynamic dns.

Thank you guys for the help in advance!

Embeds are not supported on non-standard ports. It’s expecting port 443 because it’s over HTTPS, where as you’re using port 35353.
