TWS auto-restart

[tbilloud]

Hi,

super useful project, thanks for publishing :)

I'm trying to run ibdemo.py live for several consecutive days. The job crashes when TWS auto-restarts. With _debug=True I get:

2023-08-09 20:14:00,109 ib_insync.client ERROR Peer closed connection.

Any idea?

Have you tested it with a fixed clientId?
