Kibana Index Pattern Configuration Problem

I configured Logstash as follows:

input {
file { path => "/var/log/apache2/access.log" }
}
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
}

date {
    match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
}

mutate {
    convert => {
        "response" => "integer"
        "bytes" => "integer"
    }
}

}
output {
elasticsearch {
hosts => "localhost:9200"
index => "apache-%{+YYYY.MM.dd}"
}
}

I installed and configured Apache.
When I try to configure the index in Kibana, I get the following message: The index pattern I set does not match any data stream.

I don't know where the problem lies.
Can you please help me?
