I could not call the api from my frontend

1

I deployed both my backend (fastapi) and frontend (react) to Render. When the frontend is in development server (localhost), I could call the deployed backend from render and download the video by calling the backend api. I set all the CORS policy

app = FastAPI()

origins = [
    "https://videodownload-frontend.onrender.com",  # replace with the origin of your frontend
]

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

also I did not specify any designated port to be called as I saw some posts from the community saying that not specifying ports could solve the issue. Since the backend api could be called in frontend localhost, I suspect it’s the problem with my deployed frontend but not backend. Do anyone have similar problem and how to solve it? thank you

for more details, i have asked on stackoverflow
