Aauthorize.net AIM not working on new server

I'm stump and need some help, for whatever reason Aauthorize.net AIM is not working. Configuration is ok. It's a new zencart 1.5.4 install running on an Amazon AWS E2 server.

I verified in file ssl.conf that SSLProtocol All -SSLv2 -SSLv3 is set.

Every time I try to make an order is declined but Aauthorize.net is not even see the traction so it's a communication issue. Out of like 30 attempts I did get two to go through, not sure why those went through. Paypal works so I'm not sure what the issue can be with Aauthorize.net, anyone with ideas I would appreciate the help!

Resolved the issue! It ended up being self inflicted :) I subscribe to advanced Fraud Detection Suite from Authorized.net and have forgot that I enabled the Authorized AIM IP Address filter.

It had my old server ip only and not the new one so it was blocking the new server. Once I added the new ip address of the server it processed fine.

Error code was 250 in debug logs so if you have that code you know what the issue is :)

Thank you for reporting back with a solution to your problem.
