Hi, @squivo. I completely understand how frustrating it can be to encounter an error while trying to reconnect your BMO account. Rest assured, we're here to help you overcome this hurdle so you can get back to business.
Bank error 590 typically occurs when QuickBooks Online (QBO) is unable to connect to your bank account due to an issue on the bank’s end, such as security restrictions or connectivity interruptions. In some cases, this may resolve itself after waiting a few hours.
Since the error persists whenever you try reconnecting to the bank, I highly recommend reaching out to our Live Support team.
Here's how:
- Sign in to QuickBooks Online.
- Select the Help (?) icon.
- Click on the Search tab, then select Contact Us below.
- In What can we help you with?, enter your concern and click Continue.
- Please choose your preferred options: Chat with us or request a Callback.
Our support team has the tools and expertise to address connection errors, identify specific barriers, and resolve any technical challenges. They’ll guide you step-by-step, so you can re-establish your bank connection and focus on running your business without interruptions.
