Usage Meter 3.5 SOAPFaultException

Hi,

if i add some vCenter Server Applicances  (from VCSA 5.5 to 6.5) to my new usage meter 3.5 there seems to be everything ok - the vCenters are connected on Port 443 and i can browse the vCenter inventory under the Rules Tab, so the connection seems to be fine.

However, when the usage meter starts the hourly collection there is always an errror on the Monitoring Tab:

##

ERROR [Event Monitor $VCENTER_FQDN events.EventMonitor: javax.xml.ws.soap.SOAPFaultException: Die Aufgabe wurde von einem Benutzer

##

I also receive one Mail from the usage meter for each vCenter:

##

Usage Meter is unable to collect data from VC $VCENTER_FQDN. Please resolve the error as soon as possible otherwise usage meter will stopmetering it after 24 Hours if unresolved

##

As the connections seems ok, i have no idea what could cause this problem.

Thanks,

Jan
