Ssh No route to host

I am trying to copy my Corosync key from my desktop to my laptop. sudo scp /etc/corosync/authkey mm-HP-Elit@192.168.0.10:~ What I got is this ssh: connect to host 192.168.0.10 port 22: No route to host lost connection Both of them use the same router in my house. From my desktop, I am pinging laptop ping 192.168.0.10 PING 192.168.0.10 (192.168.0.10) 56(84) bytes of data. 64 bytes from 192.168.0.10: icmp_seq=1 ttl=64 time=1.29 ms 64 bytes from 192.168.0.10: icmp_seq=2 ttl=64 time=1.08 ms 64 bytes from 192.168.0.10: icmp_seq=3 ttl=64 time=1.03 ms 64 bytes from 192.168.0.10: icmp_seq=4 ttl=64 time=1.05 ms ^C --- 192.168.0.10 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 1.039/1.118/1.298/0.110 ms 4 packets transmitted, 0 received, +4 errors, 100% packet loss, time 3004ms Telenet is refused telnet 192.168.0.10 22 Trying 192.168.0.10... telnet: Unable to connect to remote host: Connection refused My desktop IP inet 192.168.0.12/24 brd 192.168.0.255 scope global dynamic noprefixroute enp3s0 My laptop IP inet 192.168.0.10/24 brd 192.168.0.255 scope global dynamic noprefixroute wlo1 My idea was to open port 22.
