Timeout Error 10012 MT5

Hi guys

I receive quite often from broker the timeout error when I use my MT5 EA - it is on LIVE account

and it happens like this:

the order is sent to market , after 3 min I receive a Timeout Error, and then my EA tries again  - it could try 5 times

after 5 timeout tries it will stop trying, and suddenly after 30 min I can see all 5 orders filled in market. Before it tries to place again the order it checks is there is a new order on account - but no, there is none, they all somehow magically appear after 30-40 minutes.

Attached you have the image from live account how orders are being filled after 30 min, all at once and the code for sending orders.

If anyone can help me figure this out would appreciate a lot - is it from My EA or from broker?

I will pay you right away if the issue is from my EA, broker does not want to answer to my requests

it could be on ICMarkets,- prop firms: FTMO , thePropTrading, Vantage

this is the code where it waits for response - which usually comes in 3 minutes if we have timeout

bResult = OrderSend(trade_request, trade_result);
if(bResult == true && (trade_result.retcode == TRADE_RETCODE_DONE || trade_result.retcode == TRADE_RETCODE_PLACED))
                        {
                                RetVal = (int)trade_result.order;               
                                // EVERYTHING OK
                                break;
                        } else Print("Error Sending Order "+IntegerToString(trade_result.retcode));  // 10012 here comes after 3 minutes

It could happen when I try to open trade and sometimes when I try to change SL/TP

Thank you
