2018-10-31T08:00:21,259 E main [ ] Error while loading web app configuration. Shutting down, please verify the jcc properties. java.io.IOException: keys.properties does not have any user for auth prefix: cc

Have you downloaded the configuration files and put them on the machine?
If not, can you open up the manager and navigate to your Snaplex. Then click the downloads tab and download the configuration. The file should go in c:\opt\snaplogic\etc
