This problem is a little vague, but I'm hoping maybe someone has had the
same problem and knows what the solution is.
I have a BQ Centos server in which a customer is processing credit card
payments through Authorize Net's AIM method. Suddenly about a week ago it
stopped working. There is no error message, the process just hangs for a
while and then eventually goes to the next page but without any reponse from
Authorize Net.
It might seem that the problem is with Auth. Net, especially since nothing
has changed on the server. But we tried running a script from another
server that also uses auth net (a separate auth net account), It works fine
on the other server, but didn't work on the problem server. So this would
seem to indicate that the problem is with the server.
I had a similar problem a few years ago on a Windows server and don't recall
the resolution. I do recall that Authorize Net wasn't much help except to
say that the request wasn't reaching their server.
I realize there isn't much to go on, but I'm hoping just from the
description that someone might have gone through this before and knows what
to do.
