I'm getting an error when I am trying to connect my Novo bank account. The URL for it is app.banknovo.com, and it continues to throw an error (189).

I'll help you connect your bank to QuickBooks Self-Employed (QBSE), @matt125.

It could be that the stored cache and cookies are the reason why you're getting an error when connecting your bank to QuickBooks. Let me share some basic troubleshooting steps that will help you fix this issue. Let's start by:

1. Access your QBSE account using a private browser. This doesn't save your site data and visited pages. You can press Ctrl + Shift + N for Google Chrome or Ctrl + Shift + P for Mozilla Firefox.
2. If you're able to connect your bank, let's go back to your regular browser and clear the cache to delete the junk files. If you're still getting the same error, we can use other supported browsers in the meantime. The one you're currently using may have temporary issues with QBSE.

Let me also provide you a link to check if your browser is compatible with QuickBooks: Fixit.intuit.com.

Once you successfully connect your bank to QuickBooks, the system will automatically download your recent bank transactions.  All you have to do is approve the way QBSE categorizes them. You check out these steps how to categorize them in QuickBooks.

You can also manually export the transactions from your bank. Just follow these steps on how to download your transactions as a CSV file.

I'm always here to help if you have any other concerns or questions. Just tag my name in the comment section and I'll get back to you as soon as I can.

Hi from Novo! This issue should be resolved, please let us know if you experience any further issues with your transactions syncing.
