Signature Issue

fetching balance: binance {"code":-2015,"msg":"Invalid API-key, IP, or permissions for action."} AuthenticationError: binance {"code":-2015,"msg":"Invalid API-key, IP, or permissions for action."}

when fetching balance, this issue encountered.
But when fetching ticker, price, market... , this issue never encoutered according to the same api key.

Hi @jupiter950, correct this is because ticker price and market are public endpoints, so no api key is needed.
Have you verified the api key is correct?

Api key is right
