Error when reconnecting

[mpolavieja]

Hello,

I am using ib-insync 0.9.86 on a windows server 2022 machine. On the daily restart, I reconnect automatically to TWS using the following code (core is an object that inherits from IB class):

def _connect_to_broker():
    ''' Tries to connect to Interactive Brokers '''
    global log   
    global configurationBase
    core.disconnect()
    currentReconnect = 1
    while True:
        try:
            connection_loss_seconds = time.time() - core.last_connection_time
            core.connect("127.0.0.1", port=7497, clientId=configurationBase['client_tws'], timeout=5)
            if core.isConnected():
                text = 'BOT CONNECTED SUCCESFULLY'
                print('{} {}'.format(datetime.now().strftime('%Y-%m-%d %H:%M:%S'), text))
                log.info(text)
                core.last_connection_time = time.time()
                if conection_loss_seconds > configurationBase['max_connection_loss_seconds']:  
                    text = 'BOT RESTARTING STRATEGIES. Disconnected for {} seconds.'
                                  .format(round(connection_loss_seconds))
                    print(text)
                    log.info(text)
                    core.cancel_all_orders()
                    core.parameters.reset()        
                break
        except Exception as e:
            text = 'Not possible to connect on attempt {}. Next attempt in {} seconds.'.format(
                currentReconnect, configurationBase['reconnection_seconds']
            )
            print(text)
            log.error(text)
            currentReconnect += 1
            core.sleep(configurationBase['reconnection_seconds'])

And below is the error I am always getting in the console (I've been unable to handle the error through the except clause). I am pretty sure there are no other instances of TWS running. Despite the error, everything seems to work properly, but I am not comfortable at all not knowing why this is happening and not being able to handle the error:

2023-10-19 09:47:17 BOT CONNECTED SUCCESFULLY
Exception in callback _ProactorBasePipeTransport._call_connection_lost (None)
handle: Handle _ProactorBasePipeTransport._call_connection_lost(None)>
Traceback (most recent call last):

ll_connection_lost
     self._sock. shutdown (socket . SHUT_RDWR)
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

Thank you in advance for your help

Edit: I am not able to capture the error within my except clause, but If I delete my except clause, I am not able to capture the error using "disconnectedEvent" or "errorEvent" either (but I might be doing something wrong).

Since I was dealing with connection errors lately, a quick comment: I catch connection errors with the exact error name, in this case "ConnectionResetError", so this should work:

try:
    ...
except ConnectionResetError as error:
    print(f"Exception {error}")
    ...
