invalid Api-Data

Hey, i tried it several times, but it is showing me everytime, that my Data is incorrect, when I want to print the current BTC value.

    Traceback (most recent call last):
  File "C:/Users/brend/PycharmProjects/pythonProject1/Binance.py", line 10, in <module>
    print(client.get_account())

    raise BinanceAPIException(self.response)
binance.exceptions.BinanceAPIException: APIError(code=-2015): Invalid API-key, IP, or permissions for action.

Here is my code:

from binance.client import Client



#binance settings
api_key = "xxx"
api_secret = "xxx"
client = Client(api_key, api_secret)
client.API_URL = "https://testnet.binance.vision/api"
print(client.get_account())
print(client.get_asset_balance(asset='BTC'))

Could somebody please help me^^
