Getting error while to make SFTP Connection for file sharing.
 
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at Renci.SshNet.Abstractions.SocketAbstraction.Connect(IPEndPoint remoteEndpoint, TimeSpan connectTimeout) at Renci.SshNet.Session.SocketConnect(String host, Int32 port) at Renci.SshNet.Session.Connect() at Renci.SshNet.BaseClient.Connect().
 
Thanks in Advance.

    Hi,
     
    I think the problem is due to connection elements (username, port, SSH key) !
    port 22 is generally used for SFTP.
     
    Best regards,

    HI Amine and Layan, I just used the below code (DLL) for SFTP Connection,
    While Debugging I found that the Exception in the Yellow marked line Below, I have Created SFTP connection in my local server and SFTP Connection is Connected via fileZilla, May I know Whether it is Coding mistake or SFTP Setup Mistake.
