Why is it taking 3 login attempts to access my external server? SSL CA signed cert?

Hi all,

I am currently running ArcGIS Server 10.1 SP1 with the web adaptor.  Publishing and access works fine on the internal network.  However it takes 3 login attempts to access the external reverse proxy address.  It prompts me for a user name and password each time I access a folder with the services directory.  Is this something to do with not enabling SSL using a CA signed certificate?
