Question

IPN传递失败。无法连接到指定的URL。请验证该网址，然后重试。

我正在尝试使用我的Paypal ipn模拟器，但每次它给我这个错误消息，似乎ipn模拟器无法命中指定的URL，即使我确定指定的URL是正确的。任何帮助，请

您是否已将文件上传到免费的Weberver上？或免费域名？这发生在我身上，当我尝试将我的ipn脚本存储在000webhost上时，我在其他网络服务器上传输我的文件，令我惊讶的是，ipn模拟器成功地向我的ipn处理程序页面发送了一个ipn

Paypal IPN模拟器对我不起作用。我使用了两个不同的服务器，登录到外部Linux服务器（在另一个国家）和wgetting处理程序URL工作正常。使用模拟器没有收到任何信息并且模拟器页面打印“IPN Delivery Failed：I / O错误：连接超时;嵌套异常是java.net.ConnectException：连接超时”一段时间后。

Handler url是tomcat jsp页面，使用ip和hostname没有帮助。

http://myserver.com:8080/testing/paypal_IPN.jsp

如果我自己在浏览器中调用了paypal_IPN.jsp，则会调用https://www.sandbox.paypal.com/cgi-bin/webscr url并使用cmd = _notify-validate＆amp; param和jsp读取INVALID字符串的回复，因为期待'因为这无论如何都是foodoo事务。

测试商家帐户已启用IPN，IPN历史记录显示交易，尝试重新发送交易，全部失败。我的Paypal集成测试用例的大型showstopper，无法验证结帐管道，无法上线。

在商家测试应用程序中启用了IPN，但这不应该影响IPN模拟器。使用POSTFORM经典提交cgibin按钮顺利，测试签证付款确定，但即使这样，IPN处理程序url也不会被调用。 IPN历史记录显示状态失败的交易。
