Description
Hello, I connect via SFTP Renci and begin processing a file. It takes 45minutes to 1 hour and then finishes. I then try to move the file using sftpclient.Moveto but i get the error that "the session is not open". This was not an issue for smaller files that processed within a few minutes.
It seems to be timing out the connection when opened for too long. How can I extend it?
I've tried the below but it's still not working
client.KeepAliveInterval = TimeSpan.FromSeconds(30);
client.ConnectionInfo.Timeout = TimeSpan.FromMinutes(150);
client.OperationTimeout = TimeSpan.FromMinutes(150);
client.Connect();

Research direction
Start with the SFTP connection lifecycle around SftpClient.MoveTo and the KeepAliveInterval, ConnectionInfo.Timeout, and OperationTimeout settings shown in the report. Reproduce the 45–60 minute file-processing case and determine whether the session remains open afterward; done means identifying a confirmed fix or documenting the missing configuration or limitation.
