How to Resolve the QuickBooks ‘Connection has been Lost’ Error?

Here are some simple hacks that may help fix QuickBooks® ‘connection to the company file has been lost’ error:

Note: Before attempting these hacks, try restarting the Database Server Manager or moving the company file to a different folder to fix the error.

1.     Verify if QuickBooks® is Updated

QuickBooks releases updates and version upgrades. Press F2 key when QuickBooks is open on the system and check the version on the Product information window. If the software version is not up-to-date, update your QB software to the latest available version.

TIP: Once you’ve the latest software, you must also upgrade your company file so that the file can work with the new version of QuickBooks® Desktop.

2.     Restart QuickBooks®

Sometimes closing and opening the QBW file may help in solving the connectivity issue, particularly in the case of an application update.

3.     Restart your System

Note: If your system is connected to a network and you are trying to access a company file stored on another computer, make sure no one else is connected to the network before you initiate the restart process.

An application update won’t run or properly function until you restart the system. Thus, restart the system on which the QuickBooks® company file is installed and check if it resolves the issue.

4.     Test Network Connectivity

If you have stored the QBW file on another computer (the one that hosts the file), check if that computer is still connected over the network.

An effective way to test network connectivity is to try opening or to save another file on the host computer. If you’re unable to open the file, you need to set up Windows access permissions required for QB.

Note: QB does not support Wireless networking, as it is not reliable for sharing information such as the company file.

5.     Check if Portable Device is Connected

If you have saved your company file in a portable storage device (such as a USB drive, flash drive, or thumb drive), make sure the device is still connected. For this, try to:

  • Disconnect and reconnect the drive.
  • Look for QBW file on your removable drive.
  • Save another file to your drive to verify it’s working.

Also, make sure that your drive has enough free space size to store your QuickBooks company file.

6.     Turn off Power Management Settings on the Server

  • On the computer, which holds the company file, open the power management settings from the Windows Control Panel. To do so, perform the following:
  • Press the Windows key, and type Power Options.
  • Select Power Options from the search results.
  • Disable the ‘sleep’, ‘standby’, and ‘hibernation’ modes on the host computer.

TIP: For detailed information about Power Options, refer to the Windows Help and Support manual.

7.   Download the QuickBooks® Tool Hub and run QuickBooks® File Doctor

If the error persists, useQuickBooks® Tool Hub to resolve the issue. QB Tool Hub includes several tools that can help fix common QuickBooks desktop errors. Once you’ve installed the QB Tool Hub, open it and run the QuickBooks File Doctor tool. File Doctor is a built-in repair utility that can help you recover damaged company files.

Be wary, though, as the File Doctor tool has certain limitations. It does not work with QB version lower than 2016. It only helps fix errors in the Company file and may fail to repair other QuickBooks® data files. Also, running this tool often results in File Doctor has stopped responding error.

8.     Use a Reliable QuickBooks® Repair Software

You can overcome the limitations of the File Doctor tool with the help of a QuickBooks® repair software such as Stellar Repair for QuickBooks® Software. It not only repairs the company file, but it also helps resolve all errors in a QBW file. Also, it can save the QuickBooks® data from further corruption.

How is Stellar Repair for QuickBooks® Software better than the built-in File Doctor Tool?
