Errors that the QuickBooks Web Connector displays on your computer
The QuickBooks Web Connector, the application that runs on your PC or server to move data between QuickBooks Desktop and Maxio, reports its own errors separately in its Status column.
For the full list of these messages and how to resolve them, see QuickBooks Web Connector Errors.
Related information
If the Web Connector won't reconnect at all or keeps failing regardless of the specific message it shows, disconnecting and reconnecting the integration often clears the underlying issue; see Disconnecting and Reconnecting with QuickBooks Desktop.
If the Web Connector's error log looks empty even though a sync just failed, see There Are No Entries in the Web Connector Log File for why that happens.
