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!

Hi Lori86!

 

Welcome to QuickBooks Community. Allow me to help you in fixing the connection error 400.

 

QuickBooks Online allows you to be added as an accountant so you can review a client's data. If you encountered this error while accessing the client's file, it could be because of a browser error. You'll want to use an incognito window and review it from there. Incognito won't save your browsing history which can result in an error.

 

These are some of the shortcut keys:

  • Google Chrome: Ctrl + Shift + N
  • Safari 11 or newer: ⌘ + Shift + N
  • Mozilla Firefox: Ctrl + Shift + P
  • Microsoft Edge: Ctrl + Shift + P  

 

Also, you'll want to clear the cache and make sure you're using a supported and up-to-date browser. This can fix any browser-related issues.

 

If the same thing happens, you'll want to inform your client to remove you, then re-invite.

 

In addition, here are the articles for the detailed steps if you need a backup of your QuickBooks Online data:

 

Post a comment again here if you need more help with this. I'll respond as soon as I can.


This appears to be a QBO answer to a desktop problem.  They were getting the error when trying to

bring in an acct. copy of QuickBooks.  I am getting the same error when I try to bring in a clients 

acct. copy.  Suggestions (in desktop format)?
