Iâm wondering if anyone else is having the same problem Iâm having. It started a couple weeks ago. I keep getting these intermittent disconnects and reconnects all day long with IB. It seems to be happening every 3-4 minutes. I called IB about a week ago and they had me restore my settings back a few days. That didnât work. Iâm running Build 877.5 of the TWS. The java version I was using was 1.6.0_02; however, after the close today I called IB and spoke to Ray in API and he told me to uninstall that java version and downgrade to 1.5.0 update 15. I installed the 1.5.0 version but Iâm still getting the disconnects/reconnects. It happens without the API application connected so that doesnât seem to be the problem. I do get a message when the API is connected to my other program, âRejected â message must contain field #52â. Iâve never seen that message before. It makes it very difficult to use the API program when I constantly get data interruptions. If anyone has any advice I would be very appreciative. Maybe I should download the Build 877.5 again. Iâm wondering if it somehow got corrupted. It worked fine 3 weeks ago, now itâs a mess. Iâve avoided upgrading to more recent builds once I find one that works with the API program since in the past I had problems with compatibility. Ideas or advice? Thanks in advance.
