This sync error appears when an account the QuickBooks integration references, whether it's an account selected in your QuickBooks integration settings or the GL account assigned to an Item, has been deleted in QuickBooks Online. When Maxio sends a transaction that points to that account's reference ID, QuickBooks Online rejects it because the account no longer exists.
Open your QuickBooks integration settings and select a different, active account in place of the one that was deleted. Example: if the deleted account was set as the Refund Source Account, choose another account from that dropdown instead.

Anyone who manages your QuickBooks chart of accounts should confirm an account isn't referenced by the Maxio integration, either in your QuickBooks integration settings or on an Item's GL account, before deleting it in QuickBooks.
For the settings that control which QuickBooks account each transaction type syncs to, see Configure QuickBooks Integration Settings.
