And in addition to what my two predecessors already noted: the intersting log here is the scc_core.log, showing a connect attempt from the browser.

1. CC is up and running 

2. Error from Browser. I have tried from all browsers chrome,firefox and edge as well as in private windows

After changing the JDK version and using SAP supplied JDK 8 getting the below error

This is resolved had to change the JDK version as well as do a clean install
