  • Save the setup file on the desktop.
  • Once downloaded, go to the desktop and double-click on the company file.
  • Agree to the terms and agreements, then follow the instructions offered on screen.
  • Click on Finish.

Once you’ve installed the QuickBooks tool hub, you can use it to resolve QuickBooks error 6143 with the steps provided below:

  • Launch the QuickBooks tool hub from the start menu.
  • Go to the Network Issues tab.
  • Choose the appropriate tool.
  • Wait for the utility to scan your system.
  • Once the tool identifies the errors, it’ll try to apply the required solution.

While this utility doesn’t always succeed, it generally provides you with errors that may be interfering with the network.

If your internet connection isn’t configured or working properly, then your internet service provider can help. On the other hand, if the server that contains the company file isn’t responding, then your hosting provider must be contacted.

Solution 2: Scan the Program and Company Files

After checking the network connection, we’re going to check the program files and look for possible damage. Then we’ll proceed to scan the company file so that we can rule out damage to your accounting data. With the help of this process, you can eradicate QuickBooks error 6143. Here are the steps you need to perform on your own;

Note: we hope that you’ve already downloaded and installed QuickBooks desktop

  • Go to the Program Files tab.
  • Click on Scan for errors.
  • Wait for the scan to finish.

If the tool isn’t able to fix a particular program file-related error, then you can always go to the control panel and use the repair option provided in the Apps section.

This repair feature enables you to repair all the program files related to a particular software – in this case, QuickBooks desktop.

To know if QuickBooks error 6143 is caused by the company file, follow these steps:

  • Launch the QuickBooks tool hub.
  • Go to the Company File tab.

If any commonly encountered errors are found, the tool will fix them automatically. However, it won’t be able to fix any permanent damage to the company file.

Note: if you suspect that your company file is damaged, get in touch with an accounting software expert immediately.

If this file contains the wrong location of your company file, then you’re likely to get this error because QuickBooks will be looking in the wrong place for the company file. This generally happens when users manually change the location of the company file on their local desktop.

  3. Even though my Internet is working, I’m still receiving the QuickBooks desktop error 6143. What should I do?

    If none of these solutions worked despite your internet connection working, then you should simply reconfigure the windows firewall rules that may be hindering the connection to the server that contains the QuickBooks company file. Once you’ve created both inbound and outbound rules to enable QuickBooks to access the ports, you’ll be able to get back to work. But the error 6143 doesn’t often result from this issue, so it may not be a sure fix for you. Another tip here is to enter a descriptive name for the new rules so that you can go back and alter them at any moment in time.
