Date: Thu, 13 Sep 2018 13:57:46 CDT Username: Source IP: 10.101.69.143 URL: GET http://nl005382:/auth/ Category: Global NoAuth Reason: UNKNOWN Notification: GATEWAY_TIMEOUT Server is up and running and pinging . Installed keyclaok on separate VM not on wildfly server. All ports in standalone.xml is configured well . and all ports were listening though. How to resolve this error ? Thanks,
