Many readtimeout errors today (07-Jul-2020)

Hi @sujith @rakeshr

Today my program faced too many ReadTimeOut errors when querying for last traded price. Was there a problem? Despite using try/except block - the program halted. I am not sure why. Can you or anyone in this forum give some thoughts?

def get_ltp(kite, trading_exchange, contract_name):
while True:
try:
temp_list = [trading_exchange + ':' + contract_name]
ltp = kite.ltp([temp_list])
temp_list = trading_exchange + ':' + contract_name # convert temp_list to string
ltp = ltp[temp_list]['last_price']
logging.info("LTP of the contract is: %s", ltp)
return float(ltp)
except exceptions.KiteException as e:
logging.info("Exception occurred while getting ltp: \n %s", e.args)
continue

    We haven't observed any such error at our end. Anyhow, we will log today's data to see, if any.

    We logged LTP and Quote request-response for almost the whole day and weren't able to encounter anything unusual.

    ok thanks @rakeshr. I will investigate on my end and let you know if it recurs.

    To catch the read timeout exception is below good enough?
    def get_ltp(kite, trading_exchange, contract_name):
        while True:
            try:
                temp_list = [trading_exchange + ':' + contract_name]
                ltp = kite.ltp([temp_list])
                temp_list = trading_exchange + ':' + contract_name  # convert temp_list to string
                ltp = ltp[temp_list]['last_price']
                logging.info("LTP of the contract is: %s", ltp)
                return float(ltp)
            except requests.exceptions.ReadTimeout as e:
                logging.exception("Timeout Error - while getting ltp: \n %s", e)
                logging.info("Retrying")
                time.sleep(1)
                continue

    except requests.exceptions.ReadTimeout as e:
    Yeah, it's correct.
