Assuming your machine is using iptables you can check if a given ip is
actually banned there (during the period of fail2ban's supposed ban) - this
may help isolate where the problem is:
iptables -nL|grep -F ip.value.to.check
example from my server (I use syslog for f2b logging):
$ sudo grep -a "fail2ban" /var/log/syslog | tail -n1
2017-09-17 11:18:01 myserver fail2ban.actions[1594]: NOTICE [postfix] Ban
14.165.80.98
$ sudo iptables -nL | grep -F 14.165.80.98
REJECT all -- 14.165.80.98 0.0.0.0/0 reject-with
icmp-port-unreachable
