**A developer is encountering an issue with Facebook login integration in their Django application.** While the login process works perfectly when using a simple http-server setup with ngrok, the same code fails to function correctly within the Django environment.

**The problem:** When a user clicks the “Login with Facebook” button, the Facebook login popup appears as expected. However, the callback function in `FB.login` immediately returns `{authResponse: null, status: ‘unknown’}` and stops further execution, regardless of whether the user completes the login or closes the popup.

**The developer has already:**

* Implemented ngrok for secure HTTPS access.
* Added the ngrok URL to Facebook app settings, including Allowed Domains and Domain Manager.
* Confirmed their backend code correctly receives the access token when the login completes successfully.

**Potential causes:**

* Django might be interfering with the Facebook login process in some way, possibly due to security settings or conflicting libraries.

**ChatGPT’s suggestions:**

* Verify Django’s `ALLOWED_HOSTS` and `CSRF_TRUSTED_ORIGINS` settings to ensure ngrok URL is included.
* Check `SESSION_COOKIE_SECURE` and `CSRF_COOKIE_SECURE` settings for proper configuration.
* Set `SECURE_PROXY_SSL_HEADER` to handle HTTPS proxies.
* Double-check Facebook app settings, especially the redirect URI.
* Examine the browser’s network tab for errors or failed requests.

**The developer is seeking assistance from the Stack Overflow community to resolve this issue.** They are looking for insights and solutions on how to correctly integrate Facebook login within their Django application.
