Thanks. Now I just have to wait for the server to fail again.

Use:

See https://winscp.net/eng/docs/rawconfig#sessionreopenauto

Is it possible to prevent WinSCP session from reconnecting after a transfer error? We send files to a load balanced server and we are seeing periodic errors with a session connection. My code does not try to reconnect after an error, but we do see a new session being created on the load balancer when a timeout occurs.

I am also not seeing an error from TransferOperationResult, I only ever get IsSuccess true.

Thanks for your help.
