WSO2 ESB:SFTP文件传输：身份验证失败

我是WSO2的新手。我试图将带有传输vfs模块的文件从本地（windows）移动到sftp服务器。使用此代理服务，我能够达到预期的效果

你能检查一下你是否可以使用像WinSCP这样的SFTP客户端从你的ubuntu服务器连接到SFTP服务器吗？事实上，我在ubuntu服务器上没有太多的独立性。我通过Puttle连接到它，我想你可以使用终端检查连接。检查此链接@PramodyaMendis我可以在终端“sftp-oHostKeyAlgorithms=+ssh-dss-I.ssh/key.pem***********************”上使用此命令连接到服务器，您好@WaleedAhmadQureshi，您得到解决方案了吗？bcoz我面临同样的问题
