• We have a RHEL server with two versions of JBoss EAP (7.0 and 7.3) JBoss EAP 7 is using ports 9990 and 9999 both declared in ManagementRealm in management-interfaces in host.xml, JBoss EAP 7.3 is using port 9993. We can use cli with jboss 7.0 but while trying to connect to Jboss 7.3 looks like it is getting connected to Jboss 7. The following error appears while trying to connect to the server using jboss.cli.sh

Failed to connect to the controller: The controller is not available at 192.168.0.2:9993: java.net.ConnectException: WFLYPRT0053: Could not connect to remote+http://192.168.0.2:9993. The connection failed: WFLYPRT0053: Could not connect to remote+http://192.168.0.2:9993. The connection failed: Invalid response
