I am attempting to upgrade/migrate IDM 4.5.2 eDirectory 8.8.8 on SLES 11 sp3 to IDM 4.6 eDirector 9.0.2 on SLES 12 SP1

I have migrated the User App driver over to the new 4.6 server and it is started successfully. However, when I attempt to access the Landing, Dashboard, IDMProv pages I get the following

in IE
Content was blocked because it was not signed by a valid security certificate.

{"Fault":{"Code":{"Value":"Sender","Subcode":{"Val ue":"XDAS_OUT_ENTITY_NON_EXISTANT"}},"Reason":{"Te xt":"Main Not found."}}}

Any suggestions on what may be the issue?
