Invalid API Key

[nerd-lab]

Versions

OS: w10  
Python: 3.6  
krakenex: 2.1.0

What are you trying to achieve?

Getting balance of an asset with pykrakenapi

# code sample
import krakenex
from pykrakenapi import KrakenAPI

api = krakenex.API()
api.load_key('key.key')

k = KrakenAPI(api)

print(k.get_account_balance()[data['base']])

What do you expect to happen?

It prints a number

What happens instead?

I get the error that my API Key is invalid

# error message
attempt: 000 | ['EAPI:Invalid key']
attempt: 001 | ['EAPI:Invalid key']
attempt: 002 | ['EAPI:Invalid key']

etc.
It's a completely new API Key 2FA for it is disabled

Edit: When I try to do it with query_private I get an invalid nonce error. I also get the invalid nonce error with pykrakenapi

import krakenex

k = krakenex.API()
k.load_key('key.key')

data = k.query_private('Balance')
print(data)

#output
{'error': ['EAPI:Invalid nonce']}
