Thanks, J¨¹rgen.
The API and gateway logs don't show any data or errors (although we had some gateway logs from the day it worked). We're raising a ticket with IBKR.
My best hypothesis at the moment is that we might have hit a limit on scanners even though the original ones were cancelled and the clients killed[^0] -- does that chime with anyone else's experience/expectations? If so, is there an easy fix?
[^0]: While I often felt like doing this in my freelancing days, I should stress that no humans were harmed in the production of this bug.
