Error on SFTP - timeout: socket is not established

Hi am having the below issue on SFTP usage, I am getting the below error"

ERROR com.appiancorp.ps.plugins.filetransfer.sftp.ReceiveFileOverSFTP - com.jcraft.jsch.JSchException: timeout: socket is not established


for my FT_Config, I used the below details.

 cast(
 'type!{plugins.ps.appiancorp.com/.../}FT_Config',
 {
 serverHostName: "192.168.246.99",
 serverPort: 22,
 scsExternalSystemKey: <indicated in SCS>,
 usePerUserCredentials: false,
 timeout: 60000,
 keepAliveTimeout: 60000,
 activeMode: false
 }
 )

I tried the connection details on external application (Cyberduck) and was able to access the remote


thanks!
