Urgent Help Needed

URL : https://testnet.binancefuture.com/fapi/v1/exchangeInfo is working perfectly everywhere but when I try to get exchange info using testnet futures api

futures_exchange_info()

(I used python-binance module), it saw me “502 Bad Gateway” error.

Thanks in advance.

You may using mainnet API for testnet or testnet API for mainnet. You should check your keys and testnet=True parameters

From docs:
client = Client(api_key, api_secret, **testnet=True**)

or for Asynchronous client

client = await AsyncClient.create(api_key, api_secret, **testnet=True**)
