Error 42002: Could not connect to the update site

SOLVEDby TurboTaxTurboTax Windows5Updated July 27, 2021

This error occurs when checking for updates. The full message reads:

Could not connect to the update site. (Error 42002: Unable to connect to the remote server.)

Possible causes include:

  • Your computer's Internet connection, proxy settings, or router may be configured incorrectly.
  • Your Internet Service Provider (ISP) may be experiencing a technical problem.
  • A personal firewall may be blocking communication to the Internet.
  • The Intuit Update Server may be experiencing a temporary problem.


  1. Make sure your security software is configured to trust TurboTax.
  2. Check your Internet connection.
  3. Check your proxy settings:
    • Open Internet Explorer and choose Internet Options from the Tools menu.
    • Select the Connections tab, and then select the LAN settings button.
    • Clear (or select) the Automatically detect settings checkbox. (You want to change it from its original setting.)
    • Select OK twice to save your change.
  4. Check your router and then update TurboTax again.

If issues persist, it's likely that the Update Server is experiencing problems. Wait and try again later or download and install a manual update instead.
