Iframe not being rendered

I am trying to set up a very simple page that only shows an iframe.


If I open this index.html file in any browser, it works. If I run it from Apache, it works.

On Netlify, the iframe content is not displayed.

Google has not been helpful. Anyone have any tips?

Hey @fenre,

This is what I’m seeing on Firefox:

Which does look like it’s loading correctly from here. Any chance there’s a browser extension getting in the way? Any errors in your console?

I found out what the issue was. The iframed content was using http instead of https. When I added a certificate to the source server it all magically started working.

So, to sum up: The issue was caused by mixing secure (https) and insecure (http) content.
