Port Forwarding keep my port closed

[stasbar]

Hello,
I have small server in my house.
I'm able to connect to it via SSH from other devices in my LAN.
The problem is that when I try to connect to the server from outside my network. I get Connection Refused.
My port forwarding looks like this:

Protocol: TCP
From: 2022 (so it doesn't collapse with router ssh)
IP: 192.168.1.127
To: 22

Then from outside the network:
ssh 178.xx.xx.238 -p 2022
give me:
ssh: connect to host 178.xx.xx.238 port 2022: Connection refused

nmap 178.xx.xx.238 -p 2022
give me:
PORT STATE SERVICE
2022/tcp closed down

What am I doing wrong ?

need a network diagram

does your ISP setup allow ports to be forward to your router?
