I tried to clean jhub namespace and install form zero with helm but i am getting the same error. It stopped to work suddenly, and i can´t create or login any user.

This looks like a similar issue that was posted earlier related to the kubernetes version of the cluster not yet being supported by the Python client library.

@manics I think you replied to that issue and I can't find it :-/

But at the beginning it worked, suddenly stopped working!

It wasn't me, but this is the related issue: https://github.com/jupyterhub/kubespawner/issues/354

Ok, I go to close the issue, you are right @manics.

Thanks
