You cannot display a lot of websites inside an iFrame. Reason being that they send an “X-Frame-Options: SAMEORIGIN” response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.
I faced the same error when embed YouTube links. For example: https://www.youtube.com/watch?v=8WkuChVeL0s
I replaced watch?v= with embed/ so the valid link will be: https://www.youtube.com/embed/8WkuChVeL0s
It works well.
Try to apply the same rule on your case.
SAMEORIGIN
The page can only be displayed in a frame on the same origin as the page itself. The spec leaves it up to browser vendors to decide whether this option applies to the top level, the parent, or the whole chain, although it is argued that the option is not very useful unless all ancestors are also in the same origin.
