SSl Error 61 - GeoTrust SSL DV CA

I am running a citrix application on Safari and Firefox and I keep getting the error message that I have chosen not to trust GeoTrust SSL DV CA.

I have reintsalled the certificate, change the settings in KeyChain to always trust. Checked to make sure I have the root certificate installed and so forth. I have been using this Citrix App for 2 years with no problems. Funny as long as I am at work it works fine, But when I try to connect from home I get the error. Can any one help?
