Getting {'code': -403, 'message': 'You do not have permission to access this application', 's': 'error'} while accessing historical data

Hi Team,

While accessing historical data, suddenly today i am getting an error message as {'code': -403, 'message': 'You do not have permission to access this application', 's': 'error'}

However, i am able to connect to the websocket , it is working fine.

I am using python fyers-apiv3 3.0.6 version, access token was generated today.
What could be causing this error while accessing historical data?

Please guide.

regards,
Naveen
