Card declined with Authorize.net

i have tried everything i can't this to process the card. I am sure all the information i am entering is correct. i can only assume that some information is being missed sent. Please take a look at it and let me know what you think. resending link and login information.

site should be working now..

just tried it out and got this back.

"
The connection to the payment plateform did not succeed. It is often caused by the hosting company blocking external connections so you should contact him for further guidance.

i have access to the server via SSH, what should i be looking to change to get this to work?.

I am using Authorize.net and I am also getting this problem..

I "am" the hosting company and it is cPanel/WHM server with CentOS and I "do" have CSF installed. I know for a PERL script I have running on here, I had to ADD it to allow the outgoing call.

My question is please, is that I can and will not turn off the firewall (forever) but I do need to know what script I need to allow to access the "outside world" please?

BUT? I looked in the firewall records, and it says nothing about it being blocked?

Thanks again !!

Jim
