Can you try removing the port from the webhost?
It might be that the worker was killed before unregistered, you will see it there but the last update will be stuck (after 10min it will be automatically removed)
I did update it to clearml-agent 0.17.2 , however the issue still persists for this long-lasting service pod.
However, this issue is no more when trying to dynamically allocate pods using the Kubernetes Glue.k8s_glue_example.py
