I do not see any certificate error, if I follow your link, therefore I think you have still an outdated or mismatching certificate on your client PC in the Certificate store.
You could run certmgr.msc and try to delete any appearance of that machines name here.
Or it was only a temporary issue - or your computer does not trust Go Daddy as issuer (Is it listed in Trusted Root Certification Authorities?).
