When clicking on our IFS url no login page is displayed and we see a suffix added to the url e.g. #rwc.client.path#

When the user clicks on Aurena no page is displayed and the URL now has the suffix #aurena.casual#

On clicking on IFS Enterprise Explorer link again no login page and the URL now shows the suffix #rwc.client.path#

Click on IFS Aurena B2B and nothing happens other than the URL now shows the suffix #aurena.b2b#

If we add admin after the URL all the 3 options above work.

Any ideas on why and how to resolve this issue?
