Can you add a logging profile "log all requests" in the virtual server configuration under security tab and try logging in with a specific source IP and then filter in the logs for that source, so you can see what is actually going on.
at the same time, try openning the developer tool and open network tab to see what is the request and response when accessing this URL.
