This looks correct.

And yet it is wrong, look closely.
Thanks, missed it.

The access(5) manpage has an example for this
1.2.3   REJECT

The client_checks file should then be like
138.185.116       REJECT

For IP address ranges probably better use a cidr_table(5).

Still: logs showing it not working are highly welcome.
