The user sees the "Error 404 not found" screen when trying to log in to the Appsync GUI.
The following errors may be seeing in the server.log file:

Marker file E:\EMC\AppSync\jboss\.\standalone\..\applications\apollo.ear.undeployed is being added to record this fact.

This may be seen if the Appsync Server services are Started and Stopped in quick succession. There are a number of files, such as E:\EMC\AppSync\jboss\.\standalone\..\applications\apollo.ear which are deployed by the Appsync Server during startup. If the service is stopped before these files are fully deployed the Appsync Server may begin to throw this error.
When we check the location C:\EMC\AppSync\jboss\applications we should see the following 6 files in a healthy system:
When we check on a system showing the "Error 404 not found" error we should find some of these files marked as undeployed, eg "apollo.ear.undeployed ".
Workaround:
In order to resolve this issue we have to get the Appsync Server service to deploy the .EAR files. Follow the procedure outlined below to accomplish this.
When we find undeployed files in the C:\EMC\AppSync\jboss\applications folder perform below mentioned steps to resolve:
