Hello,  
I am on Ubuntu 20.04 running Logstash as a collector for syslog messages from the rest of my network. I have configured java with elevated privileges but Logstash is unable to bind UDP port 514.  
[This](https://discuss.elastic.co/t/udp-listener-died-syslog-when-running-as-a-service/128890) is a similar issue but I do not wish to use any port redirection.

Logstash input configuration:

```auto
    input {
        udp {
            type => "syslog"
            port => "514"
        }
    }

```

java elevated privileges:

```auto
    ~ sudo getcap /usr/usr/lib/jvm/java-11-openjdk-amd64/bin/java 
    /usr/lib/jvm/java-11-openjdk-amd64/bin/java = cap_net_bind_service+ep

```

Journalctl logs for Logstash:

```auto

```

Is there something i am missing?  
Any help would be appreciated.
