Invalid api_key or access_token Error While Placing Orders (Even Though Keys Are Correct)

profitbuddy

I’m getting an error when placing orders through the KiteConnect API, even though my api_key and access_token are correct.
The strange part is that the same code works perfectly on another laptop.
Also, other API calls like order_history, order_book, trades, etc. work fine — only place_order() fails.
This issue started from yesterday.

Code:

from kiteconnect import KiteConnect

kite = KiteConnect(api_key="XXXXXXXXXXX")
kite.set_access_token(access_token="XXXXXXXXXXXXX")

order = kite.place_order(tradingsymbol= 'TATASTEEL', exchange= 'NSE', transaction_type= 'BUY', quantity= 1, variety= 'REGULAR', order_type= 'MARKET', product= 'CNC')

print(order)

Error:
