Eikon API 403 Error, Application id not valid

Hi I am new to Eikon API. I used the App Key Generator to get the key and tried the set_app_key but got the 403 error. My python eikon version is 1.1.12 and below is the error msg.

# eikon API connection

import eikon as ek

_EIKON_API= 'b603fcaa78a548408cb085e13d8331a955c63fa3'

ek.set_log_level(1)

ek.set_app_key(_EIKON_API)

ek.get_timeseries('AAPL.O', interval='daily')
