You clicked Disconnect inside Forecastle
From Settings → Integrations → QuickBooks Online, the Disconnect button revokes the OAuth grant with Intuit and removes the connection from Forecastle.
The OAuth tokens between Forecastle and your QuickBooks Online company have been revoked. Forecastle can no longer read data from QuickBooks Online on your behalf, and your QuickBooks Online company has been removed from Forecastle’s connected applications.
One of the following triggered the disconnection:
From Settings → Integrations → QuickBooks Online, the Disconnect button revokes the OAuth grant with Intuit and removes the connection from Forecastle.
From Settings → Manage app connections in QuickBooks Online, removing Forecastle from your connected apps revokes the same tokens.
A password change, account closure, or Intuit-side security action can invalidate the grant. Reconnecting from Forecastle restores access.
Reconnecting takes about a minute and re-establishes the same chart-of-accounts and tracking-category mappings you had before.
