    It sounds like a temporary bug:

    https://github.com/fail2ban/fail2ban/discussions/3699

    Just add it to local configuration fail2ban.local (emphasis on .local not .conf):

    [DEFAULT]
allowipv6 = auto

    @sebres says on GitHub next Fail2ban version will suppress these warnings. So I think we can just ignore it for now unless you want to patch like above…
