-Hope this helps!
+Hope this helps!  Oh yeah ... here is how to remove a false positive!

+  fail2ban-client set ssh unbanip 10.xx.15x.12x
+  fail2ban-client unban --all
+Another method that does more than individual services, and instead zaps all records:
+  sudo systemctl stop fail2ban
+  sudo truncate -s 0 /var/log/fail2ban.log
+  sudo rm /var/lib/fail2ban/fail2ban.sqlite3
+  sudo systemctl restart fail2ban
+Systemd log issues. Change the sshd jail as follows
+  sudo nano /etc/fail2ban/jail.local
+  backend = systemd
+  #backend = %(sshd_backend)s
+Some recommend adding backend = systemd into jail.conf, but I've found that does nothing. The error over ipv6 not being set and using auto can be removed as follows:
+  sudo nano /etc/fail2ban/fail2ban.conf
+  'allowipv6 = auto'
