Why is my server showing bad request in the log as soon as it starts and it was working fine a few days ago

I deployed my Django project on Render, but every time I try to access the root URL (/), I receive a 400 Bad Request error. I have confirmed that my settings are configured with ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS to include the Render domain (challo-backend-1.onrender.com). My Redis server is configured to 127.0.0.1:6379 for Channels, and I’m using Django 5.1.2.
