I have installed performance advisor on my machine.   I downloaded the software from my data fabric manager server.  When I open up performance advisor, it asks for a server name and login credentials, which I add in, but then it comes back with an error message saying could not connect to host on port 8488.   Looking at the error details it says the server refused a connection on the indicated port.
I have different filers and all come back with the same error message.
Is there a step I have a missed, or is there anything I need to do on the filers.  Any advise.
Thanks
