"Connection refused" means nothing is listening on that port (or, less
likely, that something is actively rejecting inbound packets to that
port).

You can check like this:

   netstat -an | grep 5900

Cloud connections are often initiated from the client. Clients set up
an outbound connection, and don't listen for connections in the
"normal" way. I say this from a position of ignorance about how VNC
does things.
