Hi Simon, yes the server starts running on port 3030 but hangs on. The error
seems to be
DEBUG org.eclipse.jetty.server.AbstractConnector - Could not configure
SO_REUSEPORT to false on sun.nio.ch.ServerSocketChannelImpl[unbound]
java.lang.UnsupportedOperationException: 'SO_REUSEPORT' not supported
Any idea what might be causing this error?
Thanks a lot.
Regards, Neli.

Have you already tried accessing the server in your web browser on port
3030 to see if it responds?
