Reasons
The causes of this network connection error in QuickBooks are discussed 
below-
1. The TLS settings aren’t properly configured, which can block the 
software’s access to the internet..
2. You have installed a third-party web browser that isn’t supported for 
running QuickBooks.
3. Windows Firewall or an antivirus blocks the QuickBooks connection to 
the internet.
Solutions
You can apply these methods to repair the issues in your QuickBooks-
Solution 1- Configure the TLS settings to 
prevent QuickBooks from getting blocked
Transport Layer Security settings are referred to as TLS, a security measure used by 
windows to safeguard the system data transmitted over the internet. The TLS settings are 
responsible for preventing unauthorized access or harm to data and stopping malware or 
malicious threats from entering the system through the internet. If these settings aren’t 
correctly configured, it can block QuickBooks from establishing a connection with the 
internet. Follow these steps to configure the TLS settings in favour of QuickBooks-
1. To launch the Run window, simultaneously press the Windows key and the letter “R” on 
your keyboard.
2. Clear the auto-filled text in the search field and type inetcpl.cpl as a command.
3. An Internet properties window will open up when your press Enter.
4. Single-click the Advanced tab and scroll down the settings list to find TLS.
5. Enable TLS 1.2 with a single click on the checkbox beside it and ensure all the other 
TLS settings are disabled.
6. Save the settings by clicking Apply and try to perform the task that earlier caused this 
error in QuickBooks.
Go for the following method if you still encounter the error.
Solution 2- Set the default browser for 
your Windows
QuickBooks can develop issues while connecting to the internet if the 
browser you are using fails to execute QB functions. Due to this failed 
integration with the browser, QuickBooks will not be able to perform the 
task assigned by you. Use these steps to set the default browser in your 
Windows-
1. Run a search for ‘Default Apps’ and open its window from the search 
results.
2. Approach the Web browser option and choose from Internet Explorer or 
Microsoft Edge.
3. Retry the QuickBooks task that earlier caused this error after setting the 
default browser for your Windows.
You won’t face any problems executing the task now.
