No, there are no errors with the lines mentioned.
The error appears with a connection that matches the last line.
bash-4.4$ cat pg_hba.conf
# Do not edit this file manually!
# It will be overwritten by Patroni!
local all "postgres" peer
hostssl replication "_crunchyrepl" all cert
hostssl "postgres" "_crunchyrepl" all cert
host all "_crunchyrepl" all reject
host all "ccp_monitoring" "127.0.0.0/8" scram-sha-256
host all "ccp_monitoring" "::1/128" scram-sha-256
host all "ccp_monitoring" all reject
hostssl all all all md5 <<== user connection matching this line gives the error
