- Save and Close QuickBooks: Before proceeding with the restart, ensure all users have saved their work and closed QuickBooks on their workstations.
- Restart the Server:
- On the server hosting the QuickBooks company file, click on the Start menu or press the Windows key.
- Select “Restart” from the power options or click on the power icon and choose “Restart“.

If QuickBooks Connection Has Been Lost to Company File Error persists after restarting both the server and workstations, please proceed to the next solution.
Check Network Connection
Checking the network connection involves ensuring that your computer can communicate with other devices on the network and access the internet. Here’s how to check the network connection:
Check Physical Connections
Make sure all network cables (Ethernet or Wi-Fi) are securely plugged in. If you’re using Wi-Fi, ensure that your computer is connected to the correct Wi-Fi network and that the signal strength is strong enough.
To ping your server, you must know the IP address or the domain name of the server. To Ping in Windows, follow these steps:
Open the Command Prompt: Press the Windows key on your keyboard, type “Command Prompt,” and press Enter. Alternatively, you can use the Run dialog box by pressing Windows key + R, typing “cmd,” and hitting Enter.
Once the Command Prompt window opens, you can start pinging a target by typing “ping” followed by the IP address or domain name of the server.
To Ping in macOS, follow these steps: Open the Terminal: You can find the Terminal application in the Utilities folder within the Applications folder. You can also use Spotlight search by pressing Command + Space, typing “Terminal,” and hitting Enter.
Once the Terminal window opens, you can start pinging a target by typing “ping” followed by the IP address or domain name of the server.
You will see the ping results displayed in the Command Prompt or terminal window. The output will show you the round-trip time (in milliseconds) for each packet sent and received, as well as other information such as the number of packets sent, received, and lost. If you observe packet loss or experience a slow response, it indicates the presence of a network connectivity problem.
Check IP Address and Gateway
In the Command Prompt or Terminal, type: ipconfig
Look for the IPv4 Address and Default Gateway entries. The IPv4 Address should be a valid local IP address assigned to your computer, and the Default Gateway is the IP address of your router. If you don’t see an IP address or the address is in the form of “169.254.x.x,” it means your computer couldn’t get an IP address from the router.
Reset Network Devices
If you have a separate modem and router, unplug both devices from the power source. Wait for about 30 seconds and then plug them back in. Allow them to fully restart before testing the connection again.
Check Other Devices
Verify if other devices on your network, such as smartphones or tablets, can access the internet. If multiple devices are experiencing network issues, it’s likely a problem with the network itself.
Contact your Internet Service Provider (ISP)
If you’ve gone through all the steps and still can’t establish a network connection, contact your ISP to check if there are any network outages or if there’s an issue with your internet service.
If you can access the internet but still getting QuickBooks Connection Has Been Lost to Company File Error, please proceed to the next solution.
