spring-cloud-kubernetes-fabric8-leader: 2.0.1 - Watcher stopped unexpectedly, will restart

Hi,
Using the spring-cloud-kubernetes-fabric8-leader: 2.0.1 to determine a leader for the services in my pod.

Noticed the following warnings appearing:

021-02-05 12:19:23,429 WARN  [] [OkHttp https://172.20.0.1/...] o.s.c.k.f.l.Fabric8PodReadinessWatcher.onClose 104: Watcher stopped unexpectedly, will restart

From what I've seen in another post, in the past it would attempt an reconnect but it has been reverted.
I believe this is the suggesting going forward #1800 (comment) .

Any plans to incorporate this ?
If not any suggestions on how to address this in the meantime..

Thanks

There are a couple of related PRs related to retying failed requests related to configmaps and secrets
#648
#570

Both of them have kind of stalled out.

That said I am not entirely sure it would solve this specific problem as the exception seems to be coming from Fabric8, so it seems like the problem might be solved in Fabric8.

@ryanjbaxter Thanks for the information.. In the meantime would changing the Fabrio8io back to an earlier version cause any issues?

[ryanjbaxter]

Hard to say. I know I just updated the version and had to make some small tweaks because method signatures changed, but I am unsure if that would impact you.

I am going to close this issue for now in favor of the other issues that are already open.
