【问题描述】：
我正在使用 Delphi 10.x 和 SSL FTP 客户端代码，它在我从 OVH 服务器使用的一台 FTP SSL 服务器上运行良好。 然而，它不适用于另一个，我不明白为什么。
我有一个 10054 错误。
我在 ftptest.net 上测试过，没问题，见下文。
这是我添加到标准 FTP 客户端代码中的与 TLS/SSL 相关的代码
IdSSLIOHandlerSocketOpenSSL := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
FFtp.IOHandler := IdSSLIOHandlerSocketOpenSSL;
FFTP.UseTLS := utUseExplicitTLS;
FFTP.DataPortProtection := ftpdpsPrivate;
这里是ftptest.net的LOG文件

【问题讨论】：
-
您的代码在哪里显示您已经尝试过的内容以及失败的地方？您当前的错误处理情况如何？
-
你的 Delphi 程序是 FTP 服务器还是 FTP 客户端？
-
这是一个客户端软件。
