My goal is to display content from an external web page (company SharePoint) onto the Portal. I am trying to do this by displaying an iframe, but despite adding the solution suggested here, and adding HTTP Content Security Policy headers as well (Content-Security-Policy ), I have had no success displaying the iframe. It simply says <site-url> refused to connect. Is there another site setting (perhaps another HTTP header) I should try? I have also tried the ajax .load() method as well as trying to display the RSS feed of the site, to no avail. If anyone has a solution, it would be very much appreciated! Thank you
