You are using the GitHub auth backend, but it is not properly configured. Please check the following:

You have added {{ root_domain_uri }}/complete/github/ as the callback URL in the OAuth application in GitHub. You can create OAuth apps from GitHub's developer site.

• You have set {{ client_id_key_name }} in {{ settings_path }} and social_auth_github_secret in {{ secrets_path }} with the values from your OAuth application.

• Navigate back to the login page and attempt the GitHub auth flow again.
