The “QuickBooks connection has been lost” error is a common problem that many QuickBooks users face, particularly when they are working in multi-user mode or accessing QuickBooks from a server or networked environment. This error can cause interruptions in workflow, especially when users are attempting to access their company files or make updates in QuickBooks. It’s an issue that can be frustrating, but fortunately, it is generally fixable with the right troubleshooting steps.

In this article, we will explore the causes of the “QuickBooks connection has been lost” error, provide you with troubleshooting steps, and answer frequently asked questions to help you resolve this issue.

What is the "QuickBooks Connection Has Been Lost" Error?​

The “QuickBooks connection has been lost” error typically occurs when QuickBooks is unable to communicate with the company file or database. This can happen when QuickBooks is installed on multiple systems, and one or more of those systems lose their connection to the server or to the file itself. The error may also occur when QuickBooks is used in a multi-user environment or when QuickBooks Desktop is accessing company files located on a shared network.

This error message can appear at various times during your QuickBooks session, such as when opening the company file, while performing transactions, or even while saving your work. If not resolved, the error may continue to interfere with your ability to use QuickBooks efficiently.

Common Causes of the "QuickBooks Connection Has Been Lost" Issue​

Several factors can trigger this error message. Here are some of the most common causes:

1. Network Connection Problems: A poor or unstable network connection can cause QuickBooks to lose connection to the company file stored on a server or a shared drive. In a multi-user setup, network issues can lead to intermittent disconnections.
2. Corrupt QuickBooks Company File: If the company file is corrupted or damaged, QuickBooks may struggle to maintain a stable connection, resulting in this error.
3. Firewall or Antivirus Software: Sometimes, firewall settings or antivirus software may block QuickBooks from communicating with the company file, especially if the firewall is overly restrictive or the antivirus mistakenly identifies QuickBooks files as a threat.
4. QuickBooks Database Server Manager Issues: QuickBooks Database Server Manager helps manage multi-user environments. If this service is not running properly, or if it becomes corrupted, it can cause the “QuickBooks connection has been lost” error.
5. Outdated QuickBooks Version: Running an outdated version of QuickBooks can lead to compatibility issues with newer operating systems, other programs, or network protocols, causing connection issues.
6. Server or System Performance Issues: If the server where QuickBooks is hosted is underperforming or overloaded, it may have difficulty maintaining a stable connection with the workstations or other devices trying to access the company file.

How to Fix the "QuickBooks Connection Has Been Lost" Issue​

1. Check Your Network Connection​

The first step in resolving the issue is to ensure your network connection is stable. If QuickBooks is unable to communicate with the company file over the network, it may trigger the “connection has been lost” error.

• Verify Wi-Fi Connection: If you are using a Wi-Fi network, check the signal strength. If the Wi-Fi is weak or intermittent, consider switching to a wired Ethernet connection.
• Ping the Server: You can test the connection between your computer and the server by performing a ping test. Open the Command Prompt on Windows and type:
  pgsql
  CopyEdit
  ping <server-name>
  If the ping returns a timeout or error message, there is likely an issue with the server or network connection.

2. Restart QuickBooks Database Server Manager​

If the QuickBooks Database Server Manager is not running properly, you may experience the "connection has been lost" error. Restarting the service may help resolve the issue.

To restart the QuickBooks Database Server Manager:​

1. Press Windows + R to open the Run dialog box.
2. Type services.msc and press Enter.
3. Locate QuickBooksDBXX (XX refers to your QuickBooks version, e.g., QuickBooksDB28 for QuickBooks 2021).
4. Right-click on it and select Restart.

Once the service has been restarted, try reconnecting to your company file to see if the issue has been resolved.
