Atp.Net.SftpException: Key exchange failed

0
Hi, I am not able to connect to the SFTP server. I am getting the error messages as "Atp.Net.SftpException: Key exchange failed. Requested service is not implemented. ---> Atp.Net.SshException: Key exchange failed. Requested service is not implemented." But when I connect using the WinSCP FTP client it works fine. Could you please help me out on this. Thanks, wask

I have the same issue of getting the same error. I tried the latest ComponentPro.Sftp library (v7.2.x) and still getting the same error.

We would recommend upgrading to the latest one since your version is quite old. It is dated back years ago.

  not sure if you have resolved it or not. What I did was to set the config keyexchangealgorithm to diffehellmanroup14sha1 and then it worked. alexnycheung 6/17/2020 7:48:51 PM
