Hello, @sevenwithfaith.

 

Most of the time, error 400 means that the server is unable to process the request being sent due to an issue that is perceived by the server (corrupted). If you're trying to connect your bank, we can perform some steps to isolate the problem. First, log in to your bank's website to check if you're getting the same error. If the issue persists, the error may be coming from your bank. You may reach out to them to investigate this further.

 

On the other hand, you can try manually updating your bank account to refresh the connection between QuickBooks and your financial institution.

 

Here's how:

 

  1. Go to the Banking tab.
  2. Select the blue tile at the top for the bank account you want to update.
  3. Click the Update button. If you see a message about additional authentication, follow the on-screen instructions. Not all banks require this, but some do for added peace of mind.

I'm also adding this article for your reference about fixing banking errors in QuickBooks Online.

Getting this error when adding a new employee's w-4 info

You did not respond to the question.  This has nothing to do with ON_LINE.  The error is coming when trying to download an Accountant's copy (QBKS 2024 version).  This is from the superior product.. Desktop!. So any thoughts on this error for Desktop?


Hello there, DSGcpa.

 

I'm here to provide some information about the connection error and guide you on how to fix it.

 

The Connection Error (400) you encountered while attempting to download an Accountant's copy in QuickBooks Desktop is usually caused by a problem with the network or internet connection. There are a few troubleshooting steps we can perform to fix this. 

 

First, ensure that you have a stable and reliable internet connection. If you are connected via Wi-Fi, try connecting with an Ethernet cable for a more stable connection.

 

If you are already using a wired internet connection and are still getting the error, you can temporarily disable your antivirus or firewall. These settings can sometimes cause issues with QuickBooks Desktop's connection. After you've disabled them, download the accountant's copy again. Here's an article you can use as a reference: Set up firewall and security settings for QuickBooks Desktop

 

Also, make sure to update QuickBooks Desktop to the latest release. This will help ensure that you have the most up-to-date software version with the latest bug fixes, security patches, and enhancements.

 

Let me know if you still have other concerns or any QuickBooks Desktop-related questions. I'll be here to assist. Keep safe!
