[Proftpd-user] SFTP Client : SocketError: WSAECONNRESET An existing connection was forcibly closed by the remote host.

We have a customer SFTP client that experiences this error  " SocketError: WSAECONNRESET An existing connection was forcibly closed by the remote host."
they are running the SFTP process inside MS SQL Server (SSIS).  I have examined our server side log and do not see the server sending a disconnect to the client.  So I am guessing that a router/firewall in between is terminating the socket.   Can that be the case?
They are actively downloading data but this error always pop up around after 10 minutes of data transfer when a rekey is  happening  

On our server, we have a barebone configuration.  We do not have SFTPClientAlive defined.   Will it help of SFTPClientAlive is set? 
thanks
