Authorize.net SIM issue

[sonicparke]

This issue developed sometime last week. Whenever a customer places an order they are receiving the following email from Authorize.net:




**Please DO NOT REPLY to this message. E-mail [email protected] if you
have any questions.

Authorize.Net Merchant,

Your script timed out while we were trying to post transaction results to
it.
Transaction ID: *removed*
Transaction Result: This transaction has been approved.

The following message was displayed to the customer:

------------------------------An error occurred while trying to report
this transaction to the merchant. An e-mail has been sent to the merchant
informing them of the error. The following is the result of the attempt to
charge your credit card.

This transaction has been approved.

It is advisable for you to contact the merchant to verify that you will
receive the product or service.

Authorize.net's support says this but I'm not sure I know how to fix the issue:


Greetings from Authorize.Net!

When Authorize.net is responding back to a script on your server, our system
waits 10 seconds for a response. If we do not get a response in 10 seconds,
our server will time out and display an error page. The first thing that you
will need to look for is the order that your script executes. It is very
important that something is printed to the screen before any other process
is started. If your script prints to the screen first, we will recognize
that you are receiving the information. The most effective method would be
to PRINT the headers, and a line of text such as "Processing, please wait."

To resolve this issue:

-Check that your script permissions are correct and that it can accept a
HTTPS POST.
-Check that the script is not completing other functions before writing to
the screen, such as writing to a database or sending emails.
- Please check to see if there are different processes that are used in your
script for approvals, declines, or errors. Be sure to check each process to
be sure that each process will write to the screen before any other
functions.
- Check if your script is using redirects immediately upon receipt of the
response from our servers. Redirects are discouraged because they can
potentially interfere with the process.

***On occasion, timeouts will occur that are outside of the control of your
script or our servers. Typical reasons for these timeouts are Internet
traffic, your server is overloaded or malfunctioning, or Internet routing
issues. Depending upon your server location and what route is used to send
data, it is possible that you may occasionally receive the message you are
seeing.
Thank you for contacting our customer service group.
Please let us know if there is anything we can do to help you in the future.





Why would this kinda thing just all of the sudden start happening?

Thanks,

Why would this kinda thing just all of the sudden start happening?

Most likely a result of a change on your webserver by your hosting company.
Perhaps they changed some CURL settings or some firewall configuration settings. Might be related to timeouts, connections, software versions, etc on the server/firewall setup.

What version of Zen Cart are you using? Which Authorize.net module are you using?
Who is your hosting company?

I recommend talking to your hosting company to find out what may have changed with respect to CURL and/or firewall and/or other server configuration details. Maybe they upgraded PHP or something and missed a setting.

[sonicparke]

Thanks for the response.
We're using 1.3.7.
I'm not sure how to tell what Authorize.net module I'm using.
hagenhosting.com is the host.

We'll try to get with the host and see if anythign changed.

I'm not sure how to tell what Authorize.net module I'm using.

In your Zen Cart Admin->Modules->Payment, which authorize.net module is active? Is it the AIM module, or the other one ?

[sonicparke]

It's not the AIM module. It's the other one.

If everything was working fine before and the problem just started happening -- and no changes were made by you -- then the problem is most likely as described by Authorize.net.

***On occasion, timeouts will occur that are outside of the control of your
script or our servers. Typical reasons for these timeouts are Internet
traffic, your server is overloaded or malfunctioning, or Internet routing
issues.

If your Hosting Control Panel lets you know the Server load, then I would do a test purchase (you buy something) and see what the Server load is and what happens. Other than that and as mentioned, talking to your Hoster would give the fastest resolution to the problem.

My host replied that nothign had changed but is requesting the url that Authorize.net is trying to reach to access the script. Any idea what that may be?

[DrByte]

I'm not sure exactly what your host is asking for.

The address that the SIM module is connecting to would be 'https://secure.authorize.net/gateway/transact.dll'

[sonicparke]

I was looking for the one that authrize.net tries to reach on the way back. It was taking longer that 10 seconds to reach my site after it processed the card therefore it was timing out.

However, I switched to the AIM module and it works fine. So for now I guess we're good. Unless something weird happens with that one.

Thanks!
