When clicking on various PCs and Servers in the ZCM web interface on 10.2.2 on Windows, I get this error in Firefox;

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

If I do this in IE, it just sits at loading forever and never displays. More and more clients are giving this result.

How do I go about fixing this one?
