Error reading SSH protocol banner

[juanqpi]

Hello, I can't solve this error.
I have followed this thread : https://stackoverflow.com/questions/25609153/paramiko-error-reading-ssh-protocol-banner
But with no success.
Below is the message I get.

Connection Test Failed!

Here is what we got instead:
Error reading SSH protocol banner

I am running Odoo in my computer inside a virtual machine. The SFTP I am trying to connect is from hostinger. I have used the same parameters in filezilla and the connection was OK.

What could be happening?
