我尝试使用 filezilla 打开我的网络托管帐户，但通过 Filezilla 打开它一直失败。它总是在说“Initializing TLS...我的托管提供商说他们能够成功登录！”之后超时！
我启用了 filezilla 中的调试和登录以获取更多详细信息，以下是调试输出的片段：

有人能告诉我出了什么问题以及我该如何解决吗？
答案1
看起来您正在以主动模式连接到 FTPS 服务器。当您连接到服务器时，服务器会使用加密数据通道进行响应。由于它是加密的，并且您无法知道它来自哪个端口，因此您的防火墙无法动态打开端口，只能假设这是来自外部的未知通信尝试。
尝试将连接设置为被动，看看是否可以解决问题。
