SSH.NET - No suitable authentication method found

Question

This is my code using SSH.NET

using (var sftp = new SftpClient(host, username, password))
{                
    sftp.Connect();  
}

It works on

Answer 1

Ok so the answer to my problem is that it wasn't an sftp server. It was a simple ftp server so i just used a webrequest.

Check the server is actually an sftp server first.
