BTW, "connection refused" always¹ means that you are able to reach the host you requested but that that host does not have a service listening on the port number you requested.

¹ Actually, this is only always true when connecting to systems that only support sockets for TCP/IP. If you program TCP/IP in some non-socket ways, then you can get control of the 3-way TCP connect handshake such that you can "listen" for connections on a port but refuse some connections (perhaps based on the source IP address / port number). But I've never seen anyone do that.
