Cannot connect to FTPS server

Thank you for your response. You are right. I was fooled because the documentation I received from the company we are trying to send the information to said it was FTPS when in fact it was SFTP. I have made the change and it is working now.

Re: Cannot connect to FTPS server

I believe that the error message is clear. It's not FTPS server, but SFTP server. Even 22 port number suggests that.

If you can connect in WinSCP GUI, the GUI can generate a code template for you:

Cannot connect to FTPS server

I am trying to connect to a remote server using FTPS. I read online that it can be done using WinSCP but I am unable to make the connection. I am running a .NET Core console application. My code and the error message are below. Thank you in advance for any help you might offer.

Error Message:
Connection failed. Timeout detected. (control connection) Connection failed. You cannot connect to an SFTP server using an FTP protocol. Please select the correct protocol.

SessionOptions sessionOptions = new SessionOptions)
{
    Protocol = Protocol.Ftp,
    HostName = "xxxxx.com",
    UserName = "yyyyyyy",
    Password = "************",
    FtpSecure = FtpSecure.Explicit,
    PortNumber = 30022,
};
session.Open(sessionOptions);   // This is where I get the error
