org.apache.kafka.connect.errors.ConnectException

*Unable to start REST server*

Samebug tips3

It might be that there's another process connecting to the same port you're trying to use, try to kill it or change the connection port.

Change the connection port and ip adress. If you're trying to connect to your server from your own computer, check if you haven't already connected to the server in another instance.
