JBoss EAP 7 intermittently fails to start with error "java.net.ConnectException: WFLYPRT0023: Could not connect to https-remoting://xx.xx.xx.xx:yy. The connection timed out"

Issue

JBoss EAP server in ServerGroup sometimes fails to start (Domain mode). Sometimes JBoss EAP is not able to start a Server in a ServerGroup. It then tries to connect to the https-remoting instead of the remoting interface. The workaround is to restart the complete JBoss Domain Controller and then the ServerGroup with the Server will start again. Getting the following errors:
