i guess you are using FileZilla, you are connecting to implicit FTPS port 990.
If you also use this port in C#, you cannot use connection as FtpEncryptionMode.Explicit .so Use connection as FtpEncryptionMode.Implicit .
if your are already using FtpEncryptionMode.Implicit try to change to FtpEncryptionMode.Explicit and try visa versa
better use connection to port 21 and keep using FtpEncryptionMode.Explicit , if that port is available.
below is the one which i am using
