Solution 1- Set up the TLS settings correctly in Windows

The TLS or Transport Layer Security helps to secure your system from unwanted threats that can enter through the internet and harm your system. As a protocol, the settings instantly break the connection or restricts access to the internet if the browser tries to connect with an unsecured website or if the settings detect any threat during the data transmission. The TLS settings can also block the access of QuickBooks to the internet leading to this error. Refer to the following steps-

  1. Go to the search panel and search for ‘Internet options.’
  2. Click on the Internet Properties option in the search result.
  3. Navigate to the Advanced tab in the Window and scroll down to view the TLS settings.
  4. Click on the TLS 1.2 checkbox to mark it.
  5. Tap Apply and then Ok to save the TLS settings.
  6. Retry accessing the internet again in QuickBooks.

If the error still comes up, try the next method.

Solution 2- Set Microsoft Edge/Internet Explorer as your default browser

You’ll most likely encounter this error due to an incompatible third-party browser accessing the internet. Intuit always recommends using the default Windows applications for performing any task. The Web browser you use can fail to perform many QB functions and raise compatibility issues in the software. A network timeout can occur while you work, leading to data loss or connection failure. You must follow the steps below if you use an unsupported browser-

  1. Type ‘Default apps’ in the search panel and open the Default apps window from the search results.
  2. Click on the Web browser option and select Microsoft Edge/Internet Explorer as the default browser for your Windows.
  3. Retry the task that earlier caused this error in QuickBooks.

The issue will be fixed after using the steps above.
