Having Problems with Zen Cart/First Data

Hey guys, I followed this tutorial here:

I made sure to follow all of the prereq’s:

- Talked to Host Gator and they said TCP Port 1129 was open

- PEM key is uploaded (what is weird is I had to rename it to just the store number for the zc_admin panel to recognize it)

- I bought an SSL cert through host gator, ran diagnostics using and everything checks out

- cURL is setup by default

This is my problem, when I test the module in testing or production modes I get:

what could be the problem?
the one and only time I got that message with a zen cart install it was on hostgator’s end, they were doing database backups
do you think it possibly has something to do with TCP Port 1129 only being open for outbound?… apparently Host Gator won’t do it bidirectionally on my reseller account… only on VPS and dedicated servers

I highly doubt everyone with zen cart/first data module has a VPS/dedicated server though right?

host gator tech tried for about an hour of troubleshooting, now he is submitting a ticket to an administrator

I might call first data again to see if they can open their firewall for the IP that my server connects to them from
I’m probably going to be collocating 2 servers in a couple months so I shouldn’t have a problem with the ports… any other ZC payment modules for CC payments that you guys can recommend until then?

(yes I already have paypal setup)

I have one of their business accounts, which is a dedicated ip, but still shared, and I have had no problem with zen cart and ports
I talked to First Data on the phone and they said it won’t work without bi-directional communication… what payment modules are you using?
