vCenter 5.1 upgrade to 6.0 precheck fails on certificate

[GreyhoundHH]

Hi,

the precheck of the upgrade fails with error:

IP Address: x.x.x.x is not present in certificate subject alt names.

Use an ip address or dns name that is present in the certificate subject alt names or regenerate ssl certificates for sso before continuing.

What can I do beside regenerating any certificates?

Any help appreciated.

Regards

Changing the value of this registry key

HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Infrastructure\SSOServer\fqdnip

from IP to FQDN and restarting the SSO-service solved the problem.
