"connection refused" by receiving RST packet means port is closed, and no
process listens on port as Ed said

look through
a) if it runs on correct port (22) and interfaces

egrep "^Port|ListenAddress" /etc/ssh/sshd_config && netstat -ntlp | grep
sshd

b) check again for running firewall rules to filter inbound traffic with
tcp-reset option (I doubt, because "ssh -X fredex at localhost" fails too)

c) test manually

nc -4vi1 localhost 22

from remote pc
nc -4vi1 192.168.2.117 22

try to restart service, then and check logs

journalctl -xb _COMM=sshd
