我正在尝试使用安装在我们的一台db服务器中的茶壶连接，但我得到以下错误。我试着在我的笔记本电脑上使用相同的.ktr文件，效果很好。。 我确信用户名和密码是正确的

java.lang.Exception： 连接到Salesforce时出错！ ; 嵌套异常是： java.net.ConnectException:连接超时：连接

Ketter似乎无法访问网络上的salesforce端点

从kettle所在的服务器尝试，打开控制台并尝试：

curl -i 'https://yourSalesforceWebservice.foo/services/Soap/u/21.0'

或

（放入域或ip）

traceroute yourSalesforceWebservice.foo
