In the past I have collected data via an IB paper-trading account but been able to access the live account separately. I was able to collect data on the live-trading account in QR v2 with no problems. When I went to reset my paper-trading credentials I received this error.
set_credentials("ibg1", username="PAPER_ACCT", trading_mode="paper")
This is a similar error that arose when I tried starting & stopping the ibg1 again.
Tried navigating to the destinations it mentioned to potentially remove them, but wasn't able to access.
