java.net.ConnectException: Connection refused

tip

First of all, check if your firewall is not blocking your connection. If it's not, you might need to explicitly set advertised.host.name to "advertised.host.name = yourIpAddress", this forces the hosts returned to be the resolvable IP address of your VM.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
