IB TWS security token asked after disconnection

Quote from travis:

In some cases (rarely but it is definitely a problem) I start my automated trading and, a few hours later, within the same session (within those 24 hours that do not have the forced disconnection), presumably after a disconnection, I get asked again for the login code from the IB security code card authentication.

What happens is I connect to my server, and see the popup window asking for the security codes, and since my trading is automated, this also means that the DDE data feed to excel has stopped (sometimes for hours) and my daily automated trading session has been compromised.

This has been happening for the past two months, at the frequency of once every two weeks, so it has happened already four times. Does anyone (from IB or forum users) know what I could do to fix this problem, which is not just my problem presumably? This is a very recent problem and before this, disconnections did not cause it, and IB TWS could get reconnected without the need for me to fill in the security codes again.

Quote from Catoosa:

I can not answer to your question but I think I am having the exact same problem. I have been getting the same disconnection and popup box asking for my security code almost every day. TWS will continue indefinitely to give me another login popup box. This disconnection is not due to the TWS reset after midnight or the TWS automated log-off once a day. This has been happening for about the last two months. I am in the USA and using TWS build 923.6.

We'll investigate this; travis and Catoosa, can you please check your PM? If anyone else has a recent example of the problem, and would be willing to provide information to diagnose it, please PM me.
 
I trade through IB and I usually run my machine about 7 hours a day and haven't had any connections issues. Am running build 918.7. Is it possible your internet provider is blowing chunks?

Maybe you have not updated. Latest version does that. (I trade several instances 24/7. And so do my traders.)

It's sure. Let me say it again: gateway and tws must never rechallenge the user, unless the application is closed by the user.

And more for IB: place an account view (copy paste tws code) on the gateway. And make optional the tws auto log off (just add 1 checkbox). Takes less than 5 minutes .

How many times this has to be said ?
 
Hi,

I also experience the TWS disconnects with the security token pop-ups. This also makes trading auto strategies difficult for me.

I had this problem for the last weeks with TWS 917 and with 921 which I upgraded to last week.

Today I sent a message to IB trough the message center and was informed that IB acknowledges this problem and that it will be solved today or early next week.

I'm on the european server and the disconnects always happen at about 06:30 CET. Sometimes the connection is re-established within a minute automatically, sometimes I have to restart TWS to get a connection.

Thanks.
 
Today I unplugged the power to my modem for about 30 seconds and was able to reproduce the TWS popup challenge box while the TWS program was still open. I tried this about 10 more times and did not get the popup challenge box. This popup problem must require certain conditions that were not existing when I tried to reproduce the problem because TWS would reestablish the connection without the challenge box as TWS should.

Yes for temporary internet disconnections, often it reconnects without rechallenging.

But occasionally it does re-challenge (even if no internet disconnection occurred). I lately get an avg of more than 3 pop-ups per day: destroying any automation.

They just need to make sure that <b>the user be never challenged again as long as the user, on his side, does not shut down completely the application</b> (gateway or tws) [make sure no rechallenge after weekends or any downtime or maintenance].

That is it. It's not rocket science.

i'm thinking that at relogin time if you still have the same ip address IB trusts your relogin effort.. dynamic ip addresses update every so often, sometimes only last for hours don't they?? Maybe a Static IP on your end would stabilize things for you.. if not then IB is really a mess..

I doubt that that is the issue.

My ip address never changes and I have the problem.
