Hello Railway Team,

I am experiencing a critical issue where my deployed Django application is unable to upload media files to any external storage service. The uploads are failing silently without crashing the app.

The Core Problem: When I try to upload an image from my Django admin, the request completes without any visible errors, but the file never arrives at the external storage provider. The application then incorrectly saves a local file path to the database instead of the external URL.

This is not a simple code or configuration error. I have spent the last two days performing exhaustive debugging, and all evidence points to a platform-level issue.

Here is a summary of the debugging steps we have already taken:

• Ruled Out Specific Service Issues: The exact same silent failure has happened with two different providers: Cloudinary (using django-cloudinary-storage) and Backblaze B2 (using django-storages and boto3). The failure is provider-agnostic.

• Ruled Out Code & Settings Issues: We created custom Django management commands (check_cloudinary_settings and check_b2_settings) and ran them inside the live container using railway run. The output from these commands 100% confirmed that my settings.py is loading the correct DEFAULT_FILE_STORAGE and all API credentials and settings from Railway's environment variables. The application code is correctly configured.

• Ruled Out Credential & Permission Issues: We have deleted and regenerated all API keys and secrets for both Cloudinary and Backblaze B2 multiple times. We have also meticulously checked all bucket settings, permissions, and CORS rules on the provider side.

• Ruled Out Library Version Conflicts: We have pinned specific, known-good versions of boto3 and django-storages in requirements.txt to eliminate any possibility of a versioning bug causing a silent failure.
