in the last days I suddenly get the following message when I start the Connection from NT to IB Simulation (Not Demo) Account:
"IB Simu: Invalid user or password, or system not available(LoginFailed)"
In the past it worked good. I checked the username and password several times. I´m using recommended TWS884. I reinstalled both, NT and TWS and also tested on another computer where it works.
What could be the mistake?
Thanks a lot.
