### What Operating System are you using (both controller, and any agents involved in the problem)?

I'm trying to make a test setup working with statsd/graphite by running the official Jenkins Docker image and the [docker-graphite-statsd](https://github.com/graphite-project/docker-graphite-statsd) image. Everything updated to latest version as of writing.

### Reproduction steps

I've created a testjob in Jenkins, and according to the Jenkins log, the plugin submits stats as expected:

```
New StatsD client created. 768177101
May 20, 2022 1:28:32 PM INFO org.jenkinsci.plugins.githubautostatus.StatsdClient$2 run
Logging value 1 for key pipeline.kilroy.stage.greetings.status.completedsuccess
May 20, 2022 1:28:32 PM INFO org.jenkinsci.plugins.githubautostatus.StatsdClient$3 run
Logging duration 392 for key pipeline.kilroy.stage.greetings.duration
May 20, 2022 1:28:33 PM INFO org.jenkinsci.plugins.workflow.job.WorkflowRun finish
Kilroy #6 completed: SUCCESS
May 20, 2022 1:28:33 PM INFO org.jenkinsci.plugins.githubautostatus.StatsdClient$2 run
Logging value 1 for key pipeline.kilroy.job.status.completedsuccess
May 20, 2022 1:28:33 PM INFO org.jenkinsci.plugins.githubautostatus.StatsdClient$3 run
Logging duration 3749 for key pipeline.kilroy.job.duration
May 20, 2022 1:28:33 PM INFO org.jenkinsci.plugins.githubautostatus.StatsdClient$3 run
Logging duration 0 for key pipeline.kilroy.job.blocked_duration
```

The stats doesn't show up in Graphite, though.

Plugin configuration points to the Docker IP of the statsd container - 172.17.0.2 in this case.

Unfortunately, the official Jenkins Docker image doesn't include the `nc` utility, but I've tested from other Docker containers on the same Docker daemon, and with these the statsd/graphite combo works fine.

### Expected Results

Stats logged in statsd/graphite.

### Actual Results

No data logged.

### Anything else?
