Elavon - Converge CURL error 56 - TCP connection reset by peer

[jeking]

My client recently changes processors to Elavon. I found and installed the module, but orders cannot be placed. Error log (gotta love those!!) says:

PHP Notice: Converge communications failure. 56 - TCP connection reset by peer in /home/outsid19/public_html/includes/modules/payment/elavon_converge.php on line 656

Hmmm.

PHP Version?
CURL version? (see Server Info page in Admin Tools menu)
OpenSSL version? (see Server Info page in Admin Tools menu)

[jeking]

PHP: 5.6.25
CURL version: 7.29.0
OpenSSL version: 1.0.1e-fips 11 Feb 2013

I've tried to simulate all kinds of bad situations to trigger teh problem, but can't.

Most articles suggest firewall issues on your site. Or outdated PHP/CURL/OpenSSL.

While the curltester script doesn't "know" about Elavon, it does test a dozen other common destinations. Give it a try and report back: /extras/curltester.php

[jeking]

curltester.php results below.

I see there are newer versions of cURL but it wasn't clear if 7.29 was still supported or not.
OpenSSL looks to be current.

Are there firewall ports that I need to confirm are open?

jim,
i think your output is not correct.

the output of yoursite.com/extras/curltester.php should look something like the attached screenshot.

best.

It's Zen Cart 1.5.3. I replaced with the curltest.php and now get something like yours.

It uses port 443, just like every other HTTPS secure communication. No special ports required.

I suppose you might be passing invalid or incorrect parameters for user/key credentials, and so it's finding a malformed request, and rejecting it outright ("bye") instead of giving a proper "hi, sorry: error, bye".

Or perhaps your Elavon account is configured to limit transactions from only a certain IP, and your server is not in that list.

[jeking]

The Elavon logging shows what looks to be a full array out.

The response back is somewhat lacking.

I'm confirming details with the client and Elavon.
