Apache服务器错误的证书链

Question

我想为我的网站安装多证书（ECC和RSA） 这是我对apache的配置：

#ECC
SSLCertificateFile ECCcertificate.crt
SSLCertificateKeyFile ECCprivate.key

#RSA
SSLCertificateFile RSAcertificate.crt
SSLCertificateKeyFile RSAprivate.key

链和证书包含在两个证书文件中：

-----BEGIN CERTIFICATE-----
ECC certificate
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
ECC chain 1
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
ECC chain 2
-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----
RSA certificate
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
RSA chain 1
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
RSA chain 2
-----END CERTIFICATE-----

我在ssllabs中测试我的网站，它说“此服务器的证书链不完整。等级上限为B.”
我的服务器返回带有RSA链的ECC证书。
