Fail2Ban blocks ip despite both ignoreself and ignoreip being set in jail.local
Solution 1:
Ignoring 192.168.2.1/32 would mean you are ignoring that IP alone. But in the logs you've shown you're banning 192.168.2.13. I think you've made a typo. I think your ignoreip should be
ignoreip = 192.168.2.13/32 ::1
