1. Can you connect with Filezilla?  
2. Try setting PreferredHostKeyAlgorithms to RSA
3. Check the server logs

1- i tried to connect with Filezila and it connected.
2- i set it and it's not work
3- when i check the server the error come as below

Matching cipher is not supported: blowfish-cbc
by (156k points)
That's weird, as blowfish-cbc is in the server's cipher list. Try setting PreferredCipherAlgorithms = SSHCipherAlgorithm.TripleDES
