I saw an error when I deployed living trade:
Algorithm.Initialize() Error: InteractiveBrokersBrokerage.CheckIbAutomaterError(): UnknownMessageWindowDetected - An unknown IB message window was detected. - Unknown message window detected: Challenge: 766 474 Change input method Stack Trace: System.Exception: InteractiveBrokersBrokerage.CheckIbAutomaterError(): UnknownMessageWindowDetected - An unknown IB message window was detected. - Unknown message window detected: Challenge: 766 474 Change input method
......Does it means you are using IBKR client to do living trade ?
Why not use web api with oatuh ? It's easier and does not need re-login/2FA every week (As I know, traderspost.io is using it). see:

Hi Jack! Here’s what’s going on with your error and your question:
1. About the Error:
The message:
means QuantConnect detected an unexpected popup or prompt from the Interactive Brokers (IBKR) client while trying to automate the login/connection process. This usually happens when something on the IBKR desktop client (IB Gateway or TWS) asks for manual intervention, which the automated system can’t handle.
2. Does QuantConnect Use the IBKR Desktop Client?
Yes, for live trading, QuantConnect currently uses the official Interactive Brokers Gateway or TWS desktop client, not the IBKR Web API with OAuth.
3. Why Not the IBKR Web API with OAuth (like traderspost.io)?
4. What to Do?
Reference from QuantConnect Docs:
Summary:
Yes, QuantConnect currently uses the IBKR client and not the Web API with OAuth. That’s why you see those popups and need to handle 2FA every week. You're correct that OAuth (with the Web API) would make live connections easier—hopefully QuantConnect will add that in the future.
If you want guidance on best practices for avoiding popups or automating reconnection, just ask!

Hi Jack! We're working on the recent auth issues with IB and will have a solution posted today.
The gateway is still the best cross platform, multi asset integration IB offers. It allows you to run LEAN on our cloud or locally with the same technology.
