Getting Disconnected At Certain Times

[eljefe6a]

I'm hitting a weird problem where ib_insync will disconnect immediately. The disconnect seems to happen starting at around 10:00-10:30 AM EST. It disconnects immediately after ib.connect. The connection works just fine up to that point in time.

This only happens with TWS and I'm using build 10.25.1n, Oct 30, 2023 4:01:24 PM on Linux. If I start using the gateway, everything starts working again. This is annoying as I'm still interacting with TWS.

Here is the connection code:

    util.logToConsole('DEBUG')
    util.startLoop()
    ib = IB()
    ib.connect('127.0.0.1', 7496, clientId=13)

Here is the last part of util.logToConsole('DEBUG'):

I spent some more time debugging this issue. The exception happens in ib.py at:

await asyncio.wait_for(self.reqExecutionsAsync(), timeout)

The exception is:

Unable to display children:Error resolving variables Traceback (most recent call last):
  File "/usr/lib/python3.11/asyncio/tasks.py", line 490, in wait_for
    return fut.result()
           ^^^^^^^^^^^^
  File "/usr/lib/python3.11/asyncio/futures.py", line 198, in result
    raise exc
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/jesse/repos/stocks/pytrader/venv/lib/python3.11/site-packages/ib_insync/ib.py", line 1782, in connectAsync

  File "/usr/lib/python3.11/asyncio/tasks.py", line 492, in wait_for
    raise exceptions.TimeoutError() from exc
TimeoutError

During handling of the above exception, another exception occurred:

没有error级别的日志吗？你这看不到问题，只知道断开连接了，如果你想要断开连接不断重连的话，设置disconnectedEvent回调事件函数就可以了

Same here. Does anyone have an idea for us?
Edit: I found a similar issue here #612 but there is no solution.

Changing the TWS version to Stable fixed the issue for me.
