Hello, @Aneal.

When connecting your bank, you'd want to make sure that your QuickBooks is updated to the latest version. Also, there are two possible reasons why you're being prompted with the error issue.

• The Bank ID is not correctly entered in QuickBooks.
• QuickBooks is not able to recognize your bank's ID code.

To resolve this error, let's perform the following troubleshooting steps:

1. Create a backup of your company file in QuickBooks.
2. Download QuickBooks Desktop latest release version.
3. Update your Internet Explorer browser to the latest version.
4. Select the correct bank account.
5. Switch between banking modes.

Also, you can try connecting your Pinnacle and Towne Bank account using a sample QuickBooks company file. Here's how:

1. Open QuickBooks.
2. Go to the File menu.
3. Select a New Company.
4. Pick Express Start.
5. Add your bank account to the Chart of Accounts in the newly created test company.
6. Set up the record for Bank Feeds.
7. Now You can download or import the.QBO.

If you're able to successfully connect your bank, you'd want to run the Rebuild Data tool. It helps resolve any possible data damage in your company file that may have caused the error.
