What is Connection error (400) and how is it fixed?

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.

 

If there's anything else you need help with, let me know by adding a comment. I'm always here for you. Have a good day!

There has to be some better answer that just hitting the update button, until it works!

I can see here how it is important to fix the correction error (400), @tgeorge. Let me add some details to help you with this. 

 

As mentioned above, you'll need first to check your bank's website. It could be that the error is coming from your bank. 

 

Otherwise, you can manually update your bank to restore the connection. You can follow the steps given by my colleague above. 

 

However, if the issue persists after doing the troubleshooting steps, I encourage you to contact our support team. They have the tools to further check your account.
