ebay sdk can't connect

Seem to be getting a connection error based on the trace but can't figure out why? Here is my simple script:

import ebaysdk
from ebaysdk.finding import Connection
from ebaysdk.exception import ConnectionError

api = Connection(config_file='ebay.yaml', domain='api.sandbox.ebay.com')

api_request = {
            #'keywords': u'niño',
            'keywords': u'GRAMMY Foundation®',
            'itemFilter': [
                {'name': 'Condition',
                 'value': 'Used'},
                {'name': 'LocatedIn',
                 'value': 'GB'},
            ],
            'affiliate': {'trackingId': 1},
            'sortOrder': 'CountryDescending',
        }


response = api.execute('findItemsAdvanced', api_request)

Here's the error:

Traceback (most recent call last): File "", line 1, in File "/opt/anaconda3/lib/python3.7/site-packages/ebaysdk/connection.py", line 127, in execute self.error_check() File "/opt/anaconda3/lib/python3.7/site-packages/ebaysdk/connection.py", line 223, in error_check raise ConnectionError(estr, self.response) ebaysdk.exception.ConnectionError: 'findItemsAdvanced: Accepted'

Here is my .yaml file:
