Azure WebJob 控制台应用程序连接到 sftp 站点

Question

I am a new to working with Azure webjob but I have come across an issue. I have a Console application written in C# in which I connect to an ftp site to download a file.

As so:

 using (var sftp = new SftpClient(host, username, password))
            {
                sftp.Connect();
                stream = new MemoryStream();
                sftp.DownloadFile(FileName, stream);
                sftp.Disconnect();
            }

When running this locally on visual studio it works fine, But once I build this and run it thru a scheduled webjob it fails to connect to the ftp site.

The logs output at this point is :

"The connection was closed by the server: Failed authentication for virtual user: Username (ProtocolError)"

Any advice on how to resolve this?

I've come across this Failed authentication for virtual user today at work. In my instance I'm trying to connect to Bloomberg's SFTP server. My machine was trying to connect to the server from behind an IP not in the IP whitelist we provided Bloomberg.
