Summary

The integration cannot re-establish the connection with QuickBooks Online if the connection is locked by another user. However, the “App” can be disconnected from within QuickBooks Online from the Apps > My Apps page. Upon manual disconnection, the integration will be able to establish a new connection to the QuickBooks Online company. Please note that QuickBooks Online permissions may require manual disconnect be done by the account that owns the connection. Your QuickBooks online configuration can sometimes disconnect, causing 500 or 401 errors when trying to run batches in Mobius. The fix would be to disconnect and then reconnect the configuration. However, if you are unable to disconnect in Mobius, you can do so in QuickBooks Online.
