Solutions
 Use the techniques given underneath to rectify the error from your QuickBooks-
Solution 1- Configure the Windows Firewall settings to stop 
them from blocking QuickBooks
You’ll most probably encounter this error while downloading software updates or 
performing a task online. This error is related to network connection issues and 
forbids the software from accessing the internet. This error code on your screen is 
an indication that the software has lost its connection with the internet. It doesn’t 
matter how much you try, you won’t be able to execute any online task until this 
error is resolved. The internet connection might break if the Windows Firewall 
restricts the software or interrupts its background processes. The following are the 
steps to fix the firewall settings:
• Go to your control panel's Windows Defender firewall settings or use the search 
bar.
• Look for QuickBooks in the list of programs and click it once.
• Click the Public & Private checkboxes to mark them.
• Save the settings and download the payroll update in QuickBooks again.
If the update is again interrupted by the error, try the next solution.
Solution 2- Set a QuickBooks-compatible web browser and 
remove temporary files
The web browser also plays a significant role in sustaining the internet connection. 
QuickBooks might struggle to run and integrate if you have a third-party browser 
installed on your computer. You must always use inbuilt OS web browsers to ensure 
the smooth functioning of QuickBooks and to prevent issues. Some temporary files 
in the browser can also become a barrier while setting up an internet connection. 
Use the following steps to configure the web browser settings-
• Go to the control panel or use the search bar to open Default Apps menu.
• Hit the Web Browser option and select Microsoft Edge/Internet Explorer as your 
default browser.
• Save the changes and open the default browser you selected.
• Press Ctrl + Shift + Delete in the browser to open the clear browsing history 
menu.
• Select temporary files, cached data, cookies, etc., and tap Clear Data.
• Reopen QuickBooks and download the payroll updates again.
