[ShichenXie]

I have create a docker image with jupyterhub, dockerspawner and nativeauthenticator. The jupyerhub server always hang up after a few time.

A demo repo is created to reproduce my issue, see GitHub - ShichenXie/jph. Please download the repo, and run docker compose up -d to start the hub server.

Anyone can help, thanks.

Hi! What do you mean by “always hang up”? Have you tried turning on debug logging? can you share your logs?

Do you have the same problem when running this example?

I modified the config based on the basic-example. It seems work fine. Thanks.
