An existing connection was forcibly closed by the remote host

Can you give us more details about this? Which API is throwing this error and let us know more about your setup and network details.

Attached code which gives error, also copied below:

while get_bn_price() >= Stoploss15:
if int(str(datetime.datetime.now().hour) + str(datetime.datetime.now().minute)) >= squareoff_time:
pos_df = get_position()
Place_Exit_orders(OPT_NAME_CE, pos_df[pos_df["tradingsymbol"]==OPT_NAME_CE]["quantity"].values[0], "Exiting all CALL positions, Market Closing : ")
print("market closing")
notification("Remaining positions exited as Market Closing, system exit")
sys.exit()
else:
print(OPT_NAME_CE, "Running, LTP :", get_bn_price(), "Target: ", round(First_Target15,1), " STOPLOSS :", Stoploss15)
pos_df = get_position()
if get_bn_price() >= First_Target15 and pos_df[pos_df["tradingsymbol"]==OPT_NAME_CE]["quantity"].values[0] == qty:
pos_df = get_position()
if pos_df.empty:
print("No active position")
elif pos_df[pos_df["tradingsymbol"]==OPT_NAME_CE]["quantity"].values[0] == qty:
Place_Exit_orders(OPT_NAME_CE, round(qty/2), "50% Target CALL profit booked : ")
print("50% Target achieved!!")
notification("50% Target booked")
else:
pos_df = get_position()
if pos_df.empty:
print("No active position")
else:
Place_Exit_orders(OPT_NAME_CE, pos_df[pos_df["tradingsymbol"]==OPT_NAME_CE]["quantity"].values[0], "Exiting all CALL positions : ")
ltp_tick = get_bn_price()
print("LTP :", get_bn_price())
notification("Remaining positions exited as Market Closing, system exit")

Thanks Rakeshr, get_position is called only before existing or entering the trade. It is important to avoid unnecessary buy or short selling. Do you think get_position is causing me connection error? I haven't received any error on the same code until a day before.

Sure, Thanks Rakesh for your response. I will have to recode to minimize the use of get_position. On "forcibly closed" error, once I entered in a trade, I stay in a loop to wait for target or stoploss which might have caused this error during waiting loop. Is there any code to stay active on server/connection ?
Connection error occurred only on 10 Nov, didnt get that error yesterday and today.

"your code tries to reuse the connection just as the server is closing it because it has been idle for too long or the local session is timed out" - referring to this, session is getting timed out, is there any way to avoid timeout?

Thanks Rakesh for your help. Appreciate your timely response and Zerodha for providing best service.
