MetaTrader 5 build 6230 + Python API 5.0.6231 — -10005 IPC timeout

New comment
 
Hello,

I am reporting a reproducible Python API IPC problem after MetaTrader 5 updated to terminal build 6230.

CURRENT ENVIRONMENT

Windows 11 x64
MetaTrader 5 terminal build: 6230
Python: 3.12.14 x64
Official MetaTrader5 Python package: 5.0.6231

The terminal is already running and connected normally.

Minimal reproduction:

import MetaTrader5 as mt5

path = r"C:\Program Files\PU Prime MT5 Terminal\terminal64.exe"

result = mt5.initialize(path=path, timeout=120000)

print(result)
print(mt5.last_error())

Result:

False
(-10005, 'IPC timeout')

The failure occurs inside initialize(), before terminal_info(), account_info(), symbol_info() or symbol_info_tick() can be called.

TESTS ALREADY PERFORMED

- explicit terminal path
- default and 120-second timeout
- portable=False
- clean terminal restart
- Python and terminal are both x64
- same Windows user
- same Windows session
- same integrity level
- IPC pipe exists and its ACL permits the current user
- official MetaTrader5 Python package 5.0.6231
- minimal reproduction without our application code

The result remains -10005.

IMPORTANT REGRESSION EVIDENCE

The same PU Prime terminal installation previously worked with:

MetaTrader 5 terminal build 6182
MetaTrader5 Python package 5.0.6180
Python 3.12.14 x64

Three independent validation cycles succeeded.

mt5.initialize() completed in approximately 2.03–2.51 ms and terminal_info() / account_info() worked correctly.

After MetaTrader LiveUpdate updated the terminal to build 6230, the Python IPC connection began consistently returning -10005.

Am observat, de asemenea, același comportament de -10005 la o altă instalare MetaTrader 5 după ce s-a actualizat la aceeași versiune 6230.

DE AȘTEPTAT:

mt5.initialize() stabilește conexiunea IPC către terminalul în rulare.

ACTUAL:

mt5.initialize() expiră cu:

(-10005, 'Timeout IPC')

A reprodus cineva asta cu versiunea terminalului 6230?

Există o regresie IPC cunoscută în versiunea 6230 sau o modificare necesară a configurației atunci când se folosește pachetul oficial Python 5.0.6231?

Dacă este util, pot oferi scriptul minim de reproducere, jurnalele terminalului și rapoartele anterioare de validare cu succes build-6182/API-5.0.6180.

Nu sunt implicate operațiuni comerciale. API-ul Python este folosit doar în citire pentru datele de piață.

Mulțumesc.
