UMP > Unified Reports displays an error: "Not Found"
From the portal logs you see the following type of errors:
19 Nov 2014 21:30:20,629 ERROR [PortalInitAction:235] Internal Server Error
19 Nov 2014 21:30:20,630 ERROR [PortalInitAction:235] javax.servlet.ServletException: java.lang.RuntimeException: Invalid host name
19 Nov 2014 21:30:28,443 ERROR [LayoutAction:872] Reject processAction for http:/<UMP>/web/guest/home on home html
from the wasp log we are seeing the following error:
Nov 19 21:30:20:688 ERROR [http-443-45, org.apache.catalina.core.ContainerBase.[wasp-engine].[localhost].[/].[I18n Servlet]] invoke() Servlet.service() for servlet I18n Servlet threw exception

Release: CNMSPP99000-8.47-Unified Infrastructure Mgmt-Server Pack-- On Prem
Another reason this can happen is that the Unified Reporter was not upgraded.
UIM and UMP were upgraded to 8.51.
Unified Reporter is still at 8.50
To resolve this run the "Unified Reporter" install for 8.51.
