Answer 1

i found the cause of this error..in my case the issue was, i added the "https://" in the host name when i removed "https://" from host name its working.
now the code look like this
string host = "xyz.in";
int port = 22;
string username = "abc";
string password = "xyz"
string SftpfolderName = "Images";
using (var client = new SftpClient(host, port, username, password))
{
client.Connect();
}
