Are you trying to use a forward proxy between the hub and your IDP, or are you trying to disable a forward proxy that’s configured by default?

Can you share your full JupyterHub configuration, including any environment variables you’ve set in your startup scripts?

Could you also turn on debug logging and share your logs?
