When SFTP send port is Configured with port number different from the port number that SFTP site is configured on.

Hi All,

Hope you are all doing well.

Below is my observation when SFTP send port is configured to run on a different port than Destination SFTP site configured port.

WinSCP.SessionRemoteException: Network error: Connection to "FTPServerIP or FTPDNSName" timed out. ---> WinSCP.SessionRemoteException: The server rejected SFTP connection, but it listens for FTP connections.

Did you want to use FTP protocol instead of SFTP? Prefer using encryption.
