BuildOn UI - Configure SCM not displayed

Problem

Unable to get Configure SCM to enter source code repo url and OAuth Token in BuildOn UI - SCM tab. 

Cause

NullpointerException in catalina.out due to an authentication encryption issue.

Fix

Ensure your hostname is resolved to correct valid ip-address. In case, if the hostname of BuildOn hosted machine resolving to loop-back ip-address (127.0.0.1) then update the hosts file with valid ip-address to the host. BuildOnUI authentication encryption will be passed to valid ip-address which has proper mac address.
