Deployment via SFTP not working

Trying to deploy apps with SC 9.6.004 via SFTP returns this error:

“Error connecting with the SFTP server
It was not possible to connect with the SFTP server. Please check the server address, the user and the password.”

Am I the only one with this error?

Testing the same address\user\password with an SFTP client works, so the problem seems to be with SC only.
I rarely use SFTP to deploy. Last time I used it it worked, but it was many months ago, hence it was with SC 9.4.xxx

I can connect to sftp, it does the whole process in the process bar, but nothing is copied at the end.

Is anyone able to deploy via SFTP with SC 9.6?

Same problem here, nothing is copied
