There are a couple of advanced torubleshooting tools for more adventurous technical users.
The first is the CLI tool.
You can run a manual QBO token refresh:
$ sudo docker exec -it generated_btcqbo_1 /bin/sh
# python3 cli.py refresh
# exit
Status of the refresh will print to screen.
If you want to print your current stored QBO API Client ID to screen, try:
$ sudo docker exec -it generated_btcqbo_1 /bin/sh
# python3 cli.py printqb
# exit
If for testing purposes you wish to wipe all QBO data completely, try:
$ sudo docker exec -it generated_btcqbo_1 /bin/sh
# python3 cli.py deletekeys
# exit
