NewFs: couldn't connect SSH: ssh: handshake failed: EOF

I am on rclone v1.39, I have two Windows 10 computers, both are using the same configuration file.
One computer copies files to my SFTP server, the other reports:
NewFs: couldn’t connect SSH: ssh: handshake failed: EOF

Any ideas?

Here’s my configuration file:
type = sftp
host =
user = Computer2
port = 2222
pass = XXXX

The rclone comand line reads like this:
set max=1M
set cfg=c:\Backup\rc-FS101.conf --log-file=c:\logs%computername%.txt --stats-log-level NOTICE
set dst=FS101:
set src=c:\users\public\desktop
rclone --config %cfg% --max-size %max% copy %src% %dst%

Hmm, that is it just closing the connection.

So I’d check out firewalling on either the Windows machine or on the ssh server.
