Agent successfully connected and online

I've set up Kubernetes. There is 1 jenkins master and when I start a job it's creating a temporary jenkins slave.

It seems to work fine. The slave starts and is connected. The job (just an 'echo' runs fine. But after that I see the following error in my Jenkins-slave logs. What's the reason for this?

JNLP agent connected from 10.xx.xxx.xxx/10.xx.xxx.xxx

HTTP ERROR 404

Is this because the slave is already shutted down (after running the job)?
