Rclone SSH connection issue

I am trying 1000+ servers to pull data from a corporate server (Linux) using Rclone, I have written a powershell wrapper as schedule task which uses Rclone to check files existing, then looks for size, then pulls files, then deletes files from corporate server, For all these actions its making multiple SSH connects and I am getting following error
"NewFs: couldn't connect SSH: ssh: handshake failed: read tcp Ipaddres of local server:57345->IP addr of corporate linux server:22: wsarecv: An existing connection was forcibly closed by the remote host."
Please help how to resolve this error

That means the other side closed the connection.

So it could be firewall, ratelimiting or something like that. Could you have overloaded the remote server?

Maybe you should use rclone rcd then use the remote control api to do your work - this will re-use ssh connections.
