AWS CloudFront - SSL Certificate Upload - [SSL: CERTIFICATE_VERIFY_FAILED]

I'm trying to Upload GoDaddy standard SSL certificate for my cloudFront,but keep ending up with this error "[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)". not sure what is the cause. Could somebody help me out?

Steps i followed :

1) Created CSR using openssl with privatekey.pem

2) Generated certificate files from godaddy (318rerddd6798e58e.crt & gd_bundle-g2-g1.crt)

3) converted both files to x509 formate using openssl (ex :openssl x509 -in 318rerddd6798e58e.crt -out 318rerddd6798e58e.pem -outform PEM)

4)trying to upload certificates using aws command tool.

C:>aws iam upload-server-certificate --server-certificate-name mycertificate --certificate-body file //318rerddd6798e58e.pem --private-key file://priv.pem --certificate-chain http://ift.tt/1vBUzbf --path /cloudfront/ssl/

ERROR : [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)

am i missing anything?
