Can you connect with any other SSH/SFTP client (= is this WinSCP problem or general connection/networking problem?)

In general, if this is home computer, the internet provider has to allow incoming connections.

Hello,

My friend have just got his server (a Windows 10 PC connected to internet).

I have installed OpenSSH on it.
The computer is open on his router. (so everyone can herazz with his pc I think)
I turned off his local firewall (he does not have antivirus on it)

But when I write his IP (what is my ip "on google").
And use username: admin, Password: admin
port: 22
I just get connection timed out.

So question.. Is there anything more I got to do?
Regards.
