I have a WAB application embedded in an iframe on a .aspx page and the app is being blocked for mixed content. I checked the 'src' link in the aspx file, and it is "https..." and I also check all of the links to the data sources in the config files, including links to images and I cannot find any un-secure links. Could this be an issue with the iframe and has anyone else encountered this before? Also the main web form where the iframe is located and the app are in the same folder on the same server, so I know the domain isn't an issue.
Any ideas would be greatly appreciated.
