Hi there, @Suzy-2019.

Thank you for posting here in the Community. I'm here to help process your payroll successfully.

QuickBooks 9000 happens if QuickBooks is not able to communicate its server. There are many reasons behind QuickBooks experiencing internet connectivity issues and fixing up these causes will automatically remove this error from the application. These are the following:

• If your internet connection is not working properly.
• Incorrect system date and time properties.
• Your Internet browser’s security certificates are expired.
• Your internet is facing network time out problem.

You need to check your system time and date settings, and change them if they are not set correctly. You can also try clearing your browser's cache and send the payroll again.

If the same thing happens, you can check this article for additional steps and resolution: Troubleshoot Payroll Service Server Error or Payroll Connection Error. The article is for QuickBooks Desktop Payroll, however, it troubleshoot on the browser's connection.

You can also get in touch with our Payroll Support if you need further assistance.
