Credit card authorization got messed up after host changed servers

Hi--

My site (http://www.car-collectibles.com) has been online and working with no problems for more than a year (Zen Cart 1.3.5). Last week I logged in, flushed the Zen Cart cache, changed some product attributes, and now my store wont process any credit cards. It gives me this error every time I try and check out:

"We apologize for the inconvenience, but we are presently unable to contact the Credit Card company for authorization. Please contact the Store Owner for payment alternatives."

I use Linkpoint for transactions and everything seems OK in the backend...any ideas? I'm losing a ton of business...

Please unzip and upload the curltest.php script from the following thread, and post the URL where it can be accessed.

I suspect your hosting company has changed something on the server, which has busted external communications.

Thanks. Uploaded it (http://www.car-collectibles.com/curltest.php) and it looks like I have no problems with cURL...

Your CURL itself is functional, but seems to be blocked for linkpoint traffic.

Attempting to connect to Linkpoint gives an error:

28 connect() timed out!

This suggests that they've got port 1129 blocked at the firewall.
Here's an FAQ: https://www.zen-cart.com/tutorials/index.php?article=298

Who's your hosting company?

OK, I'll check into it...they just moved all of their servers to a new location/company, so maybe that has something to do with it...?

My hosting company is site5.com

Looks like they SHOULD support it...

bump any more ideas??

Did you actually contact the host and make sure the port is open?

Contacted them, waiting on the response. Doubt the port is closed, but I guess I'll wait to hear from them.

There is nothing more you can do ... the server's telling you that the connection is failing.
That almost always means the port is closed.

Well, big surprsie--you were right! The ports were blacklisted all of a sudden for some unknown reason. Fixed now, works great. Thanks a ton!
