Hi!
Recently updated vCenter from 5.0 to 5.1.
Previosly UpdateManager was installed on the same machine with vCenter. With update i've moved it to another machine.
Scan entity
<hostname>
VMware vSphere Update Manager had an unknown error. Check the events and log files for details.

Service syslog on hosts works fine and sends log to the vCenter (syslog installed there).
I don't now how to fix this, all KB's doesn't helps.
