While setting up OAuthenticator for azuread by following this documentation: [Azure AD Setup — OAuthenticator](https://oauthenticator.readthedocs.io/en/latest/tutorials/provider-specific-setup/providers/azuread.html)

sudo tljh-config reload is stuck in infinite loop of: Hub not ready: (HTTP status 502)  
/opt/tljh/hub/lib/python3.10/site-packages/urllib3/connectionpool.py:1099: InsecureRequestWarning: Unverified HTTPS request is being made to host ‘127.0.0.1’. Adding certificate verification is strongly advised. See: [Advanced Usage - urllib3 0.1.dev50 documentation](https://urllib3.readthedocs.io/en/latest/advanced-usage.html#tls-warnings)  
warnings.warn(

and  
accessing the jupyterhub shows bad gateway exception in the browser. (mostly because relaod isn’t finished)

### How to reproduce

1. Create a JupyterHub
2. Enable https for it
3. In JupyterHub config:

```auto
auth:
    OAuthenticator:
        client_id: <client id created in azure ad using app registration>
        client_secret: <client secret created in azure ad using app registration>
    type: azuread
AzureAdOAuthenticator:
  tenant_id: <tenant id created in azure ad using app registration>
  scope: '[Read]'

```

1. Run: ‘sudo tljh-config reload’

Can you show us your full configuration, and your JupyterHub logs?

Sure,  
the tljh-config file looks like:

looking at the ModuleNotFoundError: No module named ‘jwt’, installed the module but that didn’t help

What are the errors in the logs _after_ you installed `jwt`? Also, is it possible for you to upgrade Python? Your logs contain some deprecation errors from `crypography` maybe due to Python `3.6`!!

When I run python --version I get Python 3.9.7.

When I install PyJWT it gets installed in ./.local/lib/python3.9/site-packages

Why does oauthenticator installation happens inside **python3.6** /site-packages? I tried installing the PyJWT package for python3.6 to satisfy the requirement but running python3.6 -m pip install PyJWT still installs the package in python3.9.7

Update: PyJWT module must be installed in the hub environment using sudo /opt/tljh/hub/bin/python3 -m pip install. I was installing this module in user environment which was not helping
