Tengo una interfaz React que realiza solicitudes a mi bot Discord.py que ejecuta FastAPI. Todo está bien en mi entorno de prueba, pero cuando implemento en mi host remoto, uvicorn se queja de

 WARNING: Invalid HTTP request received.

Además, si hago la solicitud a través de Postman, todo vuelve a funcionar bien. ¿Es este un problema con mi host o con alguna configuración de uvicorn que me falta?
