stack_handler crashes due to asyncio.exceptions.TimeoutError

[j1404]

Today (Tue 27 Feb) stack_handler crashes with the following error. This is pretty weird, since I haven't changed or updated anything and last evening everything was just fine. I'm running pst 1.71, ib-insync 0.9.86 and IB Gateway 10.24, this setup has been running fine a few months.

I can see from the IB Gateway log that client connect six times and each time lots of data is pulled from IB but for some reason the client doesn't agree. What might have caused this issue? Can it really be a timeout issue and if yes, where do I change the timeout?

It's a timeout, nothing to do with pysystemtrade, so you should be asking eithier on an insync forum or a generic TWS forum

Create a minimum example using just ibsync first.
