This is an extremely uncommon error. It indicates that the provided IP address or FQDN which resolves to the Single Sign On host was not the one used when installing Single Sign On.
In %TEMP%\VM_ssoreg.log , locate the line containing the error:
hostname in certificate didn't match: <install-configured FQDN or IP> != A or B or C
Where A was the FQDN entered when Single Sign On was installed and B and Care system-generated allowable alternatives.
Correct the configuration to use the FQDN on the right of the not equal to ( !=) sign. In most cases, use the FQDN specified during Single Sign On installation. If none of these options are possible, recover your Single Sign On SSL configuration.
