Fail2Ban with kopano-ical

noise

Hello

I successful installed kopano-ical i Ubuntu 18.04.6
and configured with nginx at the end of z-push config:

nano /etc/nginx/sites-available/z-push.conf

location /caldav {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://127.0.0.1:8080;
}

after that i wanted to configure fail2ban with kopano-ical but i stuck on the logfile at /var/log/kopano/ical.log
I doesnt print any ip adress, the log look like:

2022-06-03T23:55:50.202781: [kopano-ical|T4730] [=======] Starting kopano-ical version 11.0.2 (pid 4730 uid 0)

ical.cfg log settings:

log_method = auto
# Loglevel (0(none), 1(crit), 2(err), 3(warn), 4(notice), 5(info), 6(debug))
log_level = 3
log_file = /var/log/kopano/ical.log
#log_timestamp = yes

# The timezone of the system clock
#server_timezone = Europe/Amsterdam
# Enable the iCalendar GET method for downloading calendars
#enable_ical_get = yes

i try also syslog, and all log levels.
But no luck to show the ip adress in the logfile.

Here is also my filter and jail.local

nano /etc/fail2ban/filter.d/kopano-ical.conf
[INCLUDES]
before = common.conf

[Definition]

failregex = ^.*Login failed.*\n^.*[notice ] [::ffff:<HOST>].*$

ignoreregex =
[Init]
maxlines = 2

nano /etc/fail2ban/jail.local
[kopano-ical]

enabled = true
port = https
filter = kopano-ical
banaction = iptables-multiport
action = %(action_)s
 sendmail-whois[name=Kopano-iCal, dest=email@domain.com]
maxretry = 5
bantime  = 1800 # 30 minutes
logpath = /var/log/kopano/ical.log

what am I doing wrong?

Thanks in advance
