Hello, @v_potenza. 

Let's perform some troubleshooting steps so you can get back to working with your bank transactions seamlessly.

Before we start, bank error 185 usually occurs when your financial institution requests more information when entering your credentials. Usually, you'll be prompted to provide a one-time password (OTP) or answer security questions. 

In the meantime, try logging in to your QuickBooks Online account using a private window. Use either of these keyboard shortcuts to open an incognito window, depending on your browser:

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

Alternatively, use another supported, up-to-date browser to narrow down the results.

Once settled and done bringing your transactions into QBO, I'll include this resource if you want to organize your transactions moving forward. Check out here: Categorize and match online bank transactions in QuickBooks Online.

I'm still open to your replies if you have additional questions about connecting accounts. Have a good one.
