[Fail2ban-users] Found no accessible config files for filter, but exists

[Marco M. <mm...@do...>]

Hello!

I am trying to create a custom jail for a webserver. When restarting
config file parsing fails.

ERROR   Found no accessible config files for
'filter.d/rslight-sql.conf' under /etc/fail2ban

What causes this?

root@pi-dach:~# cat /etc/fail2ban/jail.d/rslight.conf 
[rslight]

enabled = true
findtime  = 1s
maxretry = 1
filter= rslight-sql.conf
banaction = firewallcmd-allports.conf

root@pi-dach:~# cat /etc/fail2ban/filter.d/rslight-sql.conf 
[Definition]

failregex = <HOST> .*GET .*SELECT%%20.*HTTP

The file exists and can be read by everyone:
-rw-r--r-- 1 root root 58 12. Jun 08:18
/etc/fail2ban/filter.d/rslight-sql.conf

kind regards
