Windows 10 update affecting AMEX download OL-304 error

Hi there, answers.


Thank you for posting here in the QuickBooks Community.


The error 304 that you're getting may be caused by one of the following:


  • Problem with your Internet connection.
  • A problem with the download or import format.
  • A discontinued version of Windows or QuickBooks Desktop.
  • A problem with one or more accounts in your company file.
  • A problem at your bank (sometimes referred to as your financial institution or FI).


I'd suggest performing the steps below in the order listed, retrying your download after each step before you move to the next.


First, let's enable TLS 1.2 in the latest version of Internet Explorer:


  1. Open Internet Explorer 11 and make sure you have the latest version installed.
  2. Click the Gear icon on the upper right section of Internet Explorer.
  3. Go to Internet Options, then Advanced Tab.
  4. Scroll down to the Security section.
  5. Uncheck the USE TLS 1.0 and put a check in USE TLS 1.2.
  6. Click Apply and then OK.
  7. Close all open programs.
  8. Restart your computer.

If you still receive the same error, you can proceed to the next steps.


To help you determine if the issue originates with your bank or their servers, create a new test company file.


Here's how:


  1. From the QuickBooks File menu, select New Company , then Express Start.
  2. Add the bank account which was experiencing issues and set up the account for Bank Feeds in the newly created test company,
  3. Download Bank Feed transactions to test the account.


If the error 304 still continue, this typically indicates that there is a problem at your bank. If you do NOT receive any error message, this means that the problem is not with your bank.

Please know that you're always welcome to post if you have any other concerns. Wishing you and your business continued success.
