    Hi,

    I have integrated my vbulletin forum with amember but I am having issues with payments. Some transactions seem to go through while others give errors.

    I am getting a lot of these errors:
    IPN seems to be received from unknown source, not from the paysystem <--- a LOT of these!
    Looks like an invalid IPN post - no Invoice# passed
    Curl error: Failed to connect to 2607:f8b0:4007:801::1014: Network is unreachable
    Curl error: Couldn't resolve host 'www.paypal.com'
    Curl error: Couldn't resolve host 'api-3t.paypal.com'


    Would really appreciate some help on this!

    Btw all the "IPN seems to be received from unknown source, not from the paysystem" are caused by this ip address: 173.0.81.1

    I think it might be because your list of paypal ip addresses is old? How do I go about adding 173.0.81.1 to the paypal ipn whitelist?

    Tom,
    Plugin doesn't store Paypal's IP address, it makes request by domain name, and your server is unable to lookup paypal.com, tha't why you have see that error.
