While it is possible that such an issue could prevent the iframe from showing up in some situations, networking/firewalls alone are not able to explain some of the other behaviours I have experienced with the test page. Thanks for the suggestion though!

After having tested this issue with five modern browsers on three devices and over six networks (including some public ones), I have found that on all the aforementioned devices and networks:

- The page displays naturally and without a prompt on all ancient browsers tested.

- The page displays, after first accepting a ssl warning, on most old (but not ancient) browsers tested.

- No tested, modern, browsers were able to, by default, view the page without first relaxing several security-related configuration settings.

Given that modern browsers are able to view both the target page (CC) and the host page (in-ca), given that the tested browsers accept the ssl certificate of both pages, and given that the test iframe can still be displayed by using a browser with relaxed security settings (and/or accepting various warnings), a network issue appears to be somewhat unlikely.

While it is useful to know that some people and some browsers are able to view the test, the embedding process is not very useful unless a vast majority of users are able to display the content on their main browser (something likely to be modern). Also, expecting all site users to add ssl security exceptions for a page would probably be unreasonable as well.

Would you happen to know what browser/version you tested it with? Did it first make you accept a warning about insecure content? As far as I am aware, the only commonly used browser to show the content by default is Internet Explorer 11 (although that isn't exactly modern).
