Description
I'm able to initially connect to the sftp server. However, after the initial file upload I try and reconnect to upload another file. This is when I get 'An existing connection was forcibly closed by the remote host.' The connection and upload process I'm using is very simple.
It seems like when I disconnect it's not fully disconnecting so when trying to reconnect it throws this exception.

Research direction
Start by reproducing the initial SFTP upload followed by disconnect, reconnect, and a second upload, using the connection and upload flow shown in the issue. Inspect how SSH.NET handles disconnecting and creating the next SFTP connection; done means the second upload completes without the SocketException.
