Do you have the complete certificate chain installed? If that is
installed, it could be that the certificate bundle provided by RapidSSL
doesn't have the certificates in order that GnuTLS expects them to be.

I haven't used commercial certificates with OpenSSL, but self-signed
roots with intermediate-CA's. In this setting GnuTLS requires that the
certificates are in specific order - first rootca, then the certificates
below it so that always the one following has to be signed by the
previous one. OpenSSL doesn't have this restriction if I've understood

I've used setup like this with Ubuntu's slapd package where
ca-bundle.pem is created with OpenSSL and contains multiple
certificates: rootca, subca, subsubca. slapd-server.crt is signed with

olcTLSCACertificateFile: /path/to/ca-bundle.pem
olcTLSCertificateFile: /path/to/slapd-server.crt
olcTLSCertificateKeyFile: /path/to/slapd-server.key
