The gadget displays nothing or shows a "Refused to connect" error message
Problem
Nothing is displayed in the gadget, even though a URL was entered and I can open the URL in my browser.
Reason 1
We embed external content via an iframe. This isolates Jira or Confluence from the external website. However, modern browsers introduced X-Frame-Options
header to increase security. The external website can deny embedding and we strictly follow it.
Solution
There is no solution to this problem.
Reason 2
Your Jira or Confluence is accessed via https://
but your embedded content is accessed via http://
. Modern browsers disallow this kind of mixed content
Solution
Change your gadget’s url to https://
. If the content is only available via http://
, there is no solution, unfortunately.
