I have some app, writhed on Python 3.7, that runs on ASGI and Starlette. I need app to accept only HTTP requests.
I've opened ports 443 and 80 via docker-compose and add HTTPSRedirectMiddleware to ensure that all connections will be redirected to https
docker-compose

def create_app():
app = Starlette()
app.add_exception_handler(HTTPException, error_handler)
app.add_middleware(ServerErrorMiddleware, handler=server_error_handler)
app.add_middleware(HTTPSRedirectMiddleware)
app.add_route("/", calculate, methods=["POST"])
return app
But when i try to send a POST request via postman on container running on localhost i get error that i can't connect and in logs of app i'll get
[WARNING] Invalid HTTP request received.
