While installing the QB software, I came across the QuickBooks error 404. An error message displayed on the screen that reads “QuickBooks Update Error 404.” It mainly occurs when QB software fails to complete any update or sync with the Intuit server. To resolve this error code, you must follow the troubleshooting steps mentioned below:
Initially, click on the Start icon on your desktop and type Firewall in the search box.
Then, click on Windows Firewall with Advanced Security.
Check if your Firewall setting has blocked QuickBooks services from accessing the Internet Connection.
Then, you have to remove QuickBooks services from the list of blocked applications.
If it didn’t work for you, open your antivirus application’s firewall and remove any QuickBooks service from the blocked list.
Hopefully, these steps would have helped you resolve QuickBooks error 404 without any hassle.
