推荐答案

嗯，这可能要晚了，但对于将来的访问者来说，

Well this might be late but for future visitors,

我当时发现 biz.nf 拒绝从外部来源与其数据库的任何连接，这意味着仅在 biz.nf 有权访问其数据库，但您将被拒绝.

I found out back then that biz.nf refuses any connections to it's DB from outside source which means that only the web-apps hosted on biz.nf have the access to their DB other than that you will get rejected.
