ssh: connect to host IP port 22: Connection refused

I'm trying to connect my laptop to another workstation with SSH protocol.On both of my Windows PCs I installed Ubuntu to work from the terminal (WSL).I've followed tutorials found online to do the installation and the configuration but it gave me this error.

I've already checked if the ssh service is running on both of PCs and if the port 22 is listening.

Another check:

I've also already checked the firewall with sudo ufw status and it's inactive.

With the command ifconfig I checked the IP address for Ubuntu but if I try to ping this IP my laptop doesn't find the server.

If I use the Windows IP, I can ping the server.

So it seems that the correct IP to use is the Windows IP and not the IP created for Ubuntu.

But when I do:

ssh -vvv helga_cassol@10.x.x.xx

This is the result:

OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2 15 Mar 2022debug1: Reading configuration data /etc/ssh/ssh_configdebug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf matched no filesdebug1: /etc/ssh/ssh_config line 21: Applying options for *debug2: resolve_canonicalize: hostname 10.0.0.79 is addressdebug3: expanded UserKnownHostsFile '~/.ssh/known_hosts' -> '/home/helga_cassol/.ssh/known_hosts'debug3: expanded UserKnownHostsFile '~/.ssh/known_hosts2' -> '/home/helga_cassol/.ssh/known_hosts2'debug3: ssh_connect_direct: enteringdebug1: Connecting to 10.0.0.79 [10.0.0.79] port 22.debug3: set_sock_tos: set socket 3 IP_TOS 0x10debug1: connect to address 10.0.0.79 port 22: Connection refusedssh: connect to host 10.0.0.79 port 22: Connection refused

If I use the Ubuntu IP address with the same command:

ssh helga_cassol@172.xx.xxx.xx

This is the result:

connect to host 172.xx.xxx.xx port 22: Connection timed out

Do you have some ideas?Thank you in advance.
