Nginx unavailable when I active keycloak socialbackends

[IT-META]

Hi everybody,

I have setup a keycloak server on my network for my on premise applications.

I want to use it for Inventree. I have an issue with that. When I configure this :

social_backends:
#  - 'allauth.socialaccount.providers.google'
#  - 'allauth.socialaccount.providers.github'
 - 'allauth.socialaccount.providers.keycloak'

And restart my server, I have 502 Nginx error.

But when I configured this:

social_backends:
  - 'allauth.socialaccount.providers.google'
 - 'allauth.socialaccount.providers.github'
#  - 'allauth.socialaccount.providers.keycloak'

The server is starting. I don't understand where is the problem. As someone have this issue ?

Thanks

Please at bare minimum provide an error log from the InvenTree server.
