"Connection to localhost refused", as a problem statement, is missing a
lot of information. Connecting how, to what port (if TCP/UDP), using
what software, expecting what response?

In general, something has to be listening on the interface you are
connecting to. "Connection refused" generally indicates that either
nothing is listening, or a filter of some sort is actively rejecting
connections.

Concrete example: Connecting to localhost on TCP/IP port 80 using a web
browser will get you "connection refused" unless there is a web server
running on the computer, bound to port 80 on the localhost interface.
