Fail2ban - filter setting

[valdoison]

Hello
I followed the tutorial of installation and configuration of FAIL2BAN. But it doesn't work.
I don't understand regular expressions in the filter corresponding to DOMOTICZ. The errors for brute force attacks are rather of the style:
2021-07-30 23:53:29.581 Error: Error parsing http request address: ::ffff:167.99.165.11
Which does not seem to match those of the filter.
But I may be wrong.
Kind regards
