IB credentials fail

Seems like nothing works. I entered my interactive broker credentials (paper) and got another error. This is a linux install exactly as the install docs specify. (username hidden below)

EDIT: Unlike querying for exchange information, IB credentials succeed for installation on a different machine. First machine is running Ubuntu 20.04. Second is running Ubuntu 18.04.

IB credentials now work on both machines, after restarting all the docker containers on the machine that wasn’t working.

docker-compose down; docker-compose -p quantrocket up -d
