Hi,
I’m making some tests with Yugabyte to see what is capable of and I’m struggling to be able to connect it.
I’m following the Docker-compose doc and got blocked on “Connection refused”:
yb-client-n1 | 402762 [main] INFO com.yugabyte.sample.apps.AppBase - Going to retrieve connection again: Connection to yb-tserver-n1:5433 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

I saw similar topics related to connection refused but nothing helped so far.
Any idea why the demo code is not working in my case?
Thank you
