Problem with Paypal connection - Error (28) connect() timed out!

[twi]

My understanding of those results is that where ever ipncheck was successful, you could use paypal basic (IPN) at least as far as your software is concerned. (Not sure if it establishes communication with paypal or not.). Where the paypal curl failed indicates that paypal express will likely not work. Where you ran just curltester.php, with success indicates that curl works and works with the zencart site. Where tested curl with ups, well, version used for 1.5.0 doesn't know what to do with a ups flag so defaults to zen cart. So no results related to ups there. Just that curl works. May also want to test with ssl=1 to ensure able to have ssl connection and that that is not a problem.

I have done a curl test with ssl=1
The results are the following:

REGULAR CURL TEST

That's just a test of CURL being able to reach a known good site: zen-cart.com.
So that just tells you CURL itself is fine.

CURL TEST WITH PAYPAL=1

That's your error 28-connect-timed-out that you need to get your hosting company involved to fix.

CURL TEST WITH ?ups=1

As mc12345678 said earlier, the ups=1 test doesn't do anything with the curltester script because curltester doesn't know anything about that parameter. So it just tests connectivity to zen-cart.com, just like your first test up above.

IPN CHECK


http://birthdaysextreme.net/ipncheck.php
IPN CHECK



IPNCHECK.PHP - Version 1.3.9


CURL RESPONSE RECEIVED - Communications OKAY
IPN TESTING - Response Received via CURL -- COMMUNICATIONS OKAY


IPN TESTING - Confirmation/Validation response with fsockopen(): FSOCKOPEN() RESPONSE RECEIVED - Communications OKAY
Default method likely to be used for communications is: CURL, with the fallback method being FSOCKOPEN if possible.
Script finished.

The IPNCHECK script doesn't test communications for Express Checkout.
It tests whether an IPN post-back can be performed. And that's only used for Standard transactions.
While it does test connectivity, a "pass" doesn't guarantee problem-free IPN usage.
The IPNCHECK tool doesn't verify anything with respect to your CURL problems.

It means what it says: CURL can be used to make an SSL connection to another server ... in this case it's the zen-cart.com server.
Basically it just means SSL works with CURL. That's all.

Thank you for a very clear interpretation. I will have to contact them by phone to resolve this. Based on your explanation, its not something I can fix. The host should fix this. Correct me if I am wrong.

Thank you for this explanation as well. conclusion is that there is no problem with my CURL settings. So the problem lies at: CURL TEST WITH PAYPAL=1

One side question: Does pointing you URL away to another directory, and then pointing it back to the same directory at the root cause these kinds of communication problems?

Cause what I now have is Paypal express not working and UPS mod intermittently works. I am just wondering if my actions is what caused the errors, or it was so coincidental that Paypal was having the same problems as I was trying to upgrade my sites by pointing the URLs to the finished and tested zc 1.51.

I suspect it's coincidental, not related.

[twi]

No.

I suspect it's coincidental, not related.

Thank you very much. That takes the burden away from me trying to fix my finished site and in the process destroying it. I will definitely contact hosting to look into this and won't quit pressing for it until they resolve it.

Thanks! Looks like ssl works fine:

There are several "programs" out there to install and take advantage of traceroute already available by your host if it is, otherwise had found some that use sockets calls to cycle through, if sockets is enabled.

Otherwise, I hadn't found anything for which I had enough access rights to iniatate. Be sure that if/when you do that it is tcp port 443 that is used. Port 80 (default) won't tell you anything useful.

Thanks! I ran a traceroute but it only traces from my computer to my host. AT&T was not shown in the path so they suggested I run a traceroute from my site to PayPal to see where it dies. But I don't know if/how I can do that.
