I have a VDS and SSL with GoDaddy and as well as a merchant account with Linkpoint API.

I have received a confirmation from GoDaddy that port 1129 is open.

I have installed the Linkpoint API under the Zen Cart Admin as well as installing the .pem file received.

I have enable cURL in the Admin as well as using the IP address of GoDaddy's proxy.

I am using Zen Cart 1.3.7.

I am getting a message of "We apologize for the inconvenience, but we are presently unable to contact the Credit Card company for authorization."

Any suggestions?
