The problem in your case is, that the ADFS-system is blocking the request as the system isn`t allowed to be used as an iframe.
If you have an ADFS-system on Windows Server 2019 or installed the latest patch for Windows Server 2016, there is a possibility:
- Open the PowerShell on your Windows Server as an Admin
Type the following command
Set-AdfsResponseHeaders -SetHeaderName "X-Frame-Options" -SetHeaderValue "allow-from <Confluence BaseURL>"
(Please replace the parameter <Confluence BaseURL> with the URL from your Confluence system)
You can verify the change by executing this command
After this change, you should be able to see the Collaboration Hub in your Confluence by using the HTML-macro and the iframe-parameter:
<iframe src="https://<Signavio-Server>/intralink/portal?t=<Your Workspace ID>" noborder="0" width="100%" height="800" scrolling="no" seamless></iframe>
(Please replace the parameter <Signavio-Server> with your dedicated Signavio plattform and the parameter <Your Workspace ID> with your own workspace ID (You can find the ID in the workspace information (Help - Workspace information)
