IBAPI runs only once, have to restart the kernel for it to run again

Question

im having an issue where I can run this code successfully once, but then when i want to run it again i have to completely restart the kernel for it to work again. can someone help?

the error i get at the second attempt to run is "ERROR 1 504 Not connected"

class IBApi (EWrapper, EClient):
    def __init__(self):
        EClient.__init__(self,self)
   
class Bot:
    ib = None
    def __init__(self):
        self.ib = IBApi() #creating an IBAPI client
        self.ib.connect("127.0.0.1",7496,1)
        ib_thread = threading.Thread(target=self.run_loop,daemon=True) #daemon means program will shut down immediately when program exits 
        ib_thread.start()
        time.sleep(1) 
        
        symbol = input("Please input the symbol you want to trade: ")
                
        # Create IB contract object
        contract = Contract()
        contract.symbol = symbol.upper()
        contract.secType = "STK"
        contract.exchange = "SMART"
        contract.currency = "USD"
       
                    
        #Create order object
        order = Order()
        order.orderType = "MKT" #LMT, etc. 
        order.action = "BUY" #SELL, etc.
        quantity = 1
        order.totalQuantity = quantity
        
        #Create Contract object
        contract = Contract()
        contract.symbol = symbol.upper()
        contract.secType = "STK"
        contract.exchange = "SMART"
        contract.primaryExchange = "ISLAND" #prioritizing the NASDAQ - avoids your order not getting submitted
        contract.currency = "USD"

        self.ib.placeOrder(1,contract, order)
        
     # run method - should be last    
    def run_loop(self):
        self.ib.run()
    def on_bar_update(self, reqID, time, open_ ,high , low, close, volume, wap, count):
        print(reqID)

#Start bot

bot = Bot()
