How to Fix the "QuickBooks Connection Has Been Lost" Error

Resolving the "QuickBooks Connection Has Been Lost" error requires a methodical approach. The following troubleshooting steps can help you restore the connection and get QuickBooks back up and running.

1. Check Network Connectivity

The first step in resolving this issue is to ensure that your network connection is stable and functioning correctly.

• Test Your Network: Use a network testing tool or the built-in Windows command prompt to test the stability of your network. You can use the ping command to check the connection between your workstation and the server.

  Copy code

  ping [Server_IP_Address]

  If you experience packet loss or high latency, you may need to address network issues, such as upgrading hardware or reducing network congestion.

• Restart Network Devices: Restart your router, modem, and any network switches or hubs to refresh the network connection.

Incorrect hosting settings can prevent QuickBooks from maintaining a stable connection to the company file.

• On the Server:

• On the Workstations:

  • Open QuickBooks on each workstation.
  • Go to File > Utilities.
  • If you see the option Stop Hosting Multi-User Access, do not select it. This means hosting is already disabled on the workstation, which is the correct setting.

3. Configure Firewall and Antivirus Settings

Firewalls and antivirus software can block QuickBooks from accessing the company file. Configuring these settings to allow QuickBooks can resolve the connection issue.

• Add QuickBooks as an Exception:

• Temporarily Disable Firewall/Antivirus:

  • If adding exceptions does not resolve the issue, try temporarily disabling the firewall or antivirus software and see if the connection is restored. If it is, re-enable the security software and fine-tune the settings.
