What special character are you using in your SSO password?
I take this as a given but better ask than be sorry afterwasrds: FP-CSVC01.domain.loc is actually in the subject alternate names of your SSO certificate?
What does c:\program files\vmware\infrastructure\vmware\cis\vmware-sso\ssolscli listServices https://FP-CSVC01.domain.loc:7444/lookupservice/sdk return on a admin command line? Twice error 100 or does it list some endpoints?
