Jupyterhub failed server spawning for single user while connecting to hub apis, hub environment set up is via anaconda.

Hi! Please could you:

  • Tell us about the system used to host JupyterHub
  • Tell us how your deployed JupyterHub, ideally with enough information for someone to reproduce your setup
  • Show us your configuration with secrets redacted
  • Turn on debug logging and show us the logs?

Thanks!

@manics I managed to solve it by downgrading Jupiterhub version now !

The key log here is “Generating new CONFIGPROXY_AUTH_TOKEN”, which only works when the Hub starts a new configurable-http-proxy instance on every launch. It looks like an earlier configurable-http-proxy process is left running, or something else is listening on port 8001, which is the source of the 403. Stopping that process should get it back.
