Kite API Connectivity Issue :: requests.exceptions.ConnectionError: ('Connection aborted.'...)

I faced ConnectionError issue with Kite API on 7-Aug-2025 and due to this order did not get placed. I run my script in a Windows Virtual Server. Ping tests always show as 2ms. Hence, no question or problem about connectivity from server side. Also, there is a sleep(1) in while loop in my python code, so script runs continuously till the end time.

Please note that I have already gone through a discussion that was similar to this error. The final response in that discussion was to use good internet connection. This suggestion is not applicable as I already have reliable and bullet proof internet connectivity.

Below is the error message that I received from Kite API along with python code that I use to place orders:

Error Message: requests.exceptions.ConnectionError: ('Connection aborted.', ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))

Python Code to place Orders:

Nifty_Max_Qty_Per_Order = 1800
End_Time = datetime.now().replace(hour=15, minute=15, second=10)

def Condn_Check_Shift():
    .....
    .....
    .....

def NS_PlaceSellOrder(symbolName, qty1):
    loop = int(qty1 / Nifty_Max_Qty_Per_Order)
    remainder = qty1 % Nifty_Max_Qty_Per_Order
    run = 0
    threads = []
    
    def place_order(quantity):
        kite.place_order(tradingsymbol=symbolName, exchange=kite.EXCHANGE_NFO, transaction_type=kite.TRANSACTION_TYPE_SELL, quantity=quantity, order_type=kite.ORDER_TYPE_MARKET, product=kite.PRODUCT_MIS, variety=kite.VARIETY_REGULAR)
        
    if loop > 0:
        while run < loop:
            thread = threading.Thread(target=place_order, args=(Nifty_Max_Qty_Per_Order,))
            threads.append(thread)
            thread.start()
            run += 1
            
        if remainder != 0:
            thread = threading.Thread(target=place_order, args=(remainder,))
            threads.append(thread)
            thread.start()
    else:
        thread = threading.Thread(target=place_order, args=(qty1,))
        threads.append(thread)
        thread.start()

    # Wait for all threads to finish
    for thread in threads:
        thread.join()        
    print(f"Nifty sell {symbolName} {qty1} qty {datetime.now().isoformat(' ', 'seconds')}")


NS_PlaceSellOrder('NIFTY2580724500CE', 1500)
NS_PlaceSellOrder('NIFTY2580724500PE', 1500)

while datetime.now() < End_Time:
    Condn_Check_Shift()
    sleep(1)
