What is QuickBooks Error 12029?

QuickBooks Error 12029 is an issue that users may encounter when QuickBooks fails to access the server.

It can manifest during program updates, payroll downloading, or when trying to access secured websites within QuickBooks.

Common Causes of QuickBooks Error 12029

Identifying the root causes of QuickBooks Error 12029 is the first step towards resolving it. Some of the most prevalent reasons include:

Understanding these causes provides a solid foundation for effectively troubleshooting the problem.

Troubleshooting Methods to Resolve QuickBooks Error 12029

  • Testing your internet speed to confirm if it’s running adequately.
  • Refreshing your router/modem by unplugging it for a few minutes and then reconnecting.
