WFLYPRT0023: Could not connect to remote://xxxx:9990. The connection timed out

[ray2017]

The slave host seems not able to connect to master.

I configured the following in host-slave.xml

<host name="SlaveHost" xmlns="urn:jboss:domain:4.2">

..............

<server-identities>

                    <secret value="RXZhMjAxNA=="/>

                </server-identities>

,..................

<domain-controller>

          <remote host="x.x.x.x" port="9990" security-realm="ManagementRealm" username="domaintest"/>

    </domain-controller>

<servers>

       <server name="Test02" group="cluster-ha">

       <socket-bindings port-offset="0"/>

       </server>

    </servers>

Given the port i I think you are using http-remoting as protocol so you sghould set it using the protocol attribute.

If you want to use 'remote' protocol then you have to use 9999 port.
