There is also the following message from IB:
Message from IB: Error validating request.-'ch' : cause - The API interface is currently in Read-Only mode. IB Error Code: 321. Request ID: -1. | 2023-06-13 22:35:28.277

We have no idea what "Read-Only mode" is about, but perhaps this will give some clue as to what is going on with IB (to the IB people). There really is nothing we can do for you on this. There is something strange with IB in this case, but we do not know what it is.
