[ic] AuthorizeNet sometimes works, sometimes doesn't. Can someone please help me?

[Sean Finkel]

Greetings,
I am currently hosting a customer who is using Interchange. We started 
off with CPanel (I know, I know) using Interchange 4.9. I have since 
moved everything to a new server, and ditched CPanel. I installed 
Interchange 5.2 from RPMs (RHEL 3.0) after compiling my own non-threaded 
PERL. We finally got everything working rather well, except for one 
constant problem. For whatever reason, IC sometimes does not seem to 
receive notifications from AuthorizeNet that an order was approved or 
declined. In each case, AuthorizeNet successfully charged the customer's 
card, but IC reports that an error occurred. This is intermittent and is 
hard to duplicate. Some days, the customer receives several orders with 
no problems, and the last 3 days he has received four that have resulted 
in this problem. I ensured we had the proper modules 
(Business::OnlinePayment, along with the ::AuthorizeNet module).

I turned debugging on, and uncommented the debugging statements. It 
appears all the variables being passed to AuthorizeNet are correct, but 
it seems a proper response is not being sent back. The version in the 
customer's AuthorizeNet Control Panel has been set to "3.1", as I had 
him verify this for me.

Pasted below are the debugging output of where things seem to go wrong. 
First is a transaction that executed properly. The second paste is of a 
transaction that failed. I am thinking IC might not be waiting long 
enough for an AuthorizeNet response. Is there any way to increase the 
wait time?

Good transaction:
-----------------------( snip )-------------------
Vend::Payment:debug: placing Net::SSLeay request: 
host=secure.authorize.net, port=443, script=/gateway/transact.dll
Vend::Payment:debug: values: {
 ... all the values passed to A.net. I have excluded them for the sake 
of brevity and customer privacy...
}
Vend::Payment:debug: received Net::SSLeay header: CONTENT-TYPE: text/html
DATE: Sat, 21 Aug 2004 18:20:12 GMT
SERVER: Microsoft-IIS/5.0
CONTENT-LENGTH: 322

Vend::Payment:debug: returning thing: {'result_page' => "1^_1^_1^_This 
transaction has been approved.^.....
-------------------------( /snip )------------------
I chopped off the rest of the response, as I am sure everyone has seen a 
proper response.

Now for the "failed" transaction:
-----------------------( snip )---------------------
Vend::Payment:debug: placing Net::SSLeay request: 
host=secure.authorize.net, port=443, script=/gateway/transact.dll
Vend::Payment:debug: values: {
  ... again, the actual values have been removed for brevity and privacy....
}
Vend::Payment:debug: received Net::SSLeay header:
Vend::Payment:debug: returning thing: {'result_page' => 
"",'header_string' => "",'status_line' => "",}
Vend::Payment:debug:
authorizenet page:  response:

Vend::Payment:debug: authorizenet response_reason_text= response_code:
Vend::Payment:debug: authorizenet result={
  'x_address' => undef,
  'x_city' => undef,
  'x_avs_code' => undef,
  'x_first_name' => undef,
  'x_response_reason_code' => undef,
  'x_response_reason_text' => undef,
  'x_MD5_hash' => undef,
  'x_trans_id' => undef,
  'x_description' => undef,
  'x_ship_to_country' => undef,
------------------------( /snip )------------------

I included some of the return values here so you can see what the debug 
log is showing.

It seems that AuthorizeNet is either not responding, or is taking too 
long. AuthorizeNet of course denies the problem is on their end (I tend 
to agree, my billing software has never had a single problem with their 
interface)

Can someone *please* offer any insight as to how I might remedy this 
problem? I am really at my wits end, and it's very frustrating for both 
me the host, and our customer who keeps getting failed orders, but 
charged credit cards.
