quickbooks Unable to Connect to Service ERROR: Unable to Connect to Service

If you change your LMN login credentials you will need to go to step #1 in the LMN QuickBooks Desktop Sync App and sign in again. Otherwise you may receive this error when you start the process of importing estimates into QuickBooks. It is looking back to LMN to see which estimates are ready for import, but the Sync Tool can't actually get into LMN because the username or password has changed so you will receive that error which says "unable to connect to service."
