Hello, When importing a whitelist MLE I am getting the following error: Error during communication with the host. Please verify the host parameters. NullPointerException. [MS_HOST_COMMUNICATION_ERROR] [3201] Follow attached the printscreen of the registration attempt. The server and the agent are apparently working well. I can navigate through all the tabs on the server and also issue request to the agent (including get tpm quote). The server communicate with the agent as we can see in the log below when it get the host info. Does anyone know what is the problem and how to solve it? 2016-05-17 13:37:55,840 INFO [http-bio-8443-exec-5] c.i.m.s.SecurityFilter [SecurityFilter.java:225] SecurityFilter >> org.apache.catalina.session.StandardSessionFacade@c0ffd40---- /getData/uploadWhiteListConfiguration.html whiteListConfigVO>>WhiteListConfig [biosWhiteList=true, vmmWhiteList=true, biosWLTarget=BIOS_OEM, vmmWLTarget=VMM_OEM, biosPCRs=0,17, vmmPCRs=18, hostLocation=null, registerHost=true] 2016-05-17 13:37:55,843 INFO [http-bio-8443-exec-5] c.i.m.S.ManagementConsoleServicesImpl [ManagementConsoleServicesImpl.java:70] ManagementConsoleServicesImpl.saveWhiteListConfiguration >> 2016-05-17 13:37:55,855 WARN [http-bio-8443-exec-4] c.i.m.s.a.h.IniHostRealm [IniHostRealm.java:66] IniHostRealm.allow is not set; host-based authentication disabled 2016-05-17 13:37:55,855 WARN [http-bio-8443-exec-4] c.i.m.s.LoggingAtLeastOneSuccessfulStrategy [LoggingAtLeastOneSuccessfulStrategy.java:70] no principal collection or realm names 2016-05-17 13:37:55,856 WARN [http-bio-8443-exec-4] c.i.m.s.a.x.X509AuthenticationFilter [X509AuthenticationFilter.java:277] Authorization is missing realm 2016-05-17 13:37:55,856 INFO [http-bio-8443-exec-4] c.i.m.s.a.x.X509AuthenticationFilter [X509AuthenticationFilter.java:118] X509CertificateAuthorization: Request timestamp ok 2016-05-17 13:37:55,876 INFO [http-bio-8443-exec-4] o.a.s.r.AuthorizingRealm [AuthorizingRealm.java:248] No cache or cacheManager properties have been set.
