Verify whether your browser can access secure websites.

Since QuickBooks uses Internet Explorer to access the Internet, you must first confirm that it is the default browser. Check to see whether your browser can visit protected websites if it isn’t already:-

  1. Run the TLS 1.2 utility after downloading it to your system.
  2. Now make sure that Internet Explorer is set as the default browser.

  1. Open your computer’s Internet Explorer application and select Internet Options after selecting Tools.
  2. Click on the Globe symbol on the security tab and make sure that the level of security doesn’t exceed Medium-high.
  3. Now in the Connections tab, choose Never Dial a Connection if you don’t utilize your computer’s dial-up connection. If you do, make sure to pick the right ISP and then select OK.
  4. Access the LAN settings to ensure the Use a Proxy Server checkbox is deselected, and the Automatically detect settings option is selected.
  5. Check the whole address and port if the Use a Proxy Server checkbox is selected.
  6. If the port is 80, uncheck the box; if it is any other port, leave it checked and select OK.
  7. Now click on the Restore Advanced Settings option under the Advanced tab.
  8. Verify that Use TLS 1.2 is chosen under the settings option and select OK.
