我尝试连接到一家公司的服务器，我应该在其中访问他们的数据库，但服务器向我重播以下错误消息。

Fout:   GnuTLS-fout -15: An unexpected TLS packet was received.
Fout:   Kan niet verbinden met server

我有所有登录凭据，您认为问题可能出在哪里？

看来您正在使用隐式 TLS，而不是显式 TLS。

看看FTP_over_TLS: Explicit vs Implicit FTPS :

FTPS (FTP over TLS) is served up in two incompatible modes. If using explicit FTPS, the client connects to the normal FTP port and explicitly switches into secure (TLS) mode with "AUTH TLS", whereas implicit FTPS is an older style service that assumes TLS mode right from the start of the connection (and normally listens on TCP port 990, rather than 21). In a FileZilla client this means prefixing the host with "FTPES://" to connect an "explicit" FTPS server, or "FTPS://" for the legacy "implicit" server (for which you will likely also need to set the port to 990).

在同一页面您可以找到how to setup client :

For a client to connect to a server using TLS, then the host for that connection needs to be set to FTPS. In FileZilla client this means prefixing the host with "FTPES://" for "explicit" FTPS, or "FTPS://" for the legacy "implicit" FTPS.
