    Default Paypal time out problems

    I am having problems with Paypal transactions timing out

    ie the message is either "(6) name lookup timed out" or
    Cardinal Centinel - cmpi_lookup error - 8030 - Communication Timeout Encountered

    I understand from this forum that this is caused by DNS lookup problems.

    My website host is denying that there is a problem.

    My question is .... that although my website is hosted by one set of people ... my actual domain (which lists the named servers) is purchased and held by a different hosting company.

    Could the problem lay with the people who are the custodians my domain name ?

    Correct. It's a DNS issue.

    No surprises there. However, it is impossible for us to to tell if it is thier problem, or a problem somewhere else along the line.

    No! Your domain name or nameservers only relate to connectivity to your site.


    The site itself will be using *different* name servers for outgoing connections.

    Thank you ... so it looks as if the issue is definitely with my website host. At least I dont have 2 people to deal with.

    Ive just had another fail today and the strange thing is that although my logs have the
    "(6) name lookup timed out" error message, the order was actually placed and the money has gone into my Paypal account.

    I just dont know what to do next.

    What paypal method are you using? Paypal express (which tends to not have the issue of order being placed and not being logged in the store.)

    The /extras/curltester.php script as explained at http://www.zen-cart.com/showthread.p...-Testing-Tools is provided to help diagnose communications issues with your host server.

    So, that'll help you see what issues might exist with connecting to paypal servers.

    Your "Cardinal" errors are happening when attempting to connect to https://paypal.cardinalcommerce.com/...ssormodule.asp ... which is not tested by the curltester.php script.

    Perhaps those will be helpful in demonstrating the problem to your hosting company without having to go through making transactions to test it.

    Im using Website Payment Pro and Paypal Express.

    This is the result from the test you told me about ....

    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.

    I also ran this test with ?ssl=1 and ?paypal=1 ... and both passed the test.

    includes/modules/paypal.php now set to CURL_TIMEOUT, 30 ... it was I think initially set to 5? up'd to 8, but still had timeouts so I set to this to 30.

    It there any other timeout settings I should increase ?

    They messages dont happen on every transaction, when these messages started I ran my own credit card through the website without any issue.

    CURL_TIMEOUT doesn't deal with DNS failures on the server.
    I'm inclined to not set it to a large value. It's better to get the webserver's DNS services working properly.

    As much as I hate to tell you this, your problem is related to DNS issues, and unless you are running your own server (which you aren't) there is literally *nothing* that *you* can do to resolve the issue (other than migrate to a new host).

    If you can't or don't wish to move hosts, your only other option is to keep logging the errors and forward a copy of them to the host whenever they occur, and hope that sooner or later they'll take the problem seriously and look into the matter.

    It is highly unlikely that you will be their only customer suffering from this problem.

    ToySeller -

    I'm having exactly the same issue as you - does your host company's name begin, by any chance, with 'T'?
