[Bug] There are no Workers polling the X Task Queue.

[bbkgh]

What are you really trying to do?

After some times without any changes in worker or server configs, in the web ui i see:

"There are no Workers polling the X Task Queue."

Environment is k8s.

After rollout restart of worker, it works again and error disappears.

How can we fix this issue? is there any retry/connect mechanism built in sdk?
