I need to refresh my bank account but I’m getting error messages (591). What does this mean and how is it resolved?

Hi there, @jwrichardd-hotma. We're here to ensure everything is running and working seamlessly.

May I know the name of your bank? First, I suggest signing in to your bank's website. Then, check if there are any alerts or notifications about this.

If there's no alerts about this, I recommend clearing your browser's cache and cookies. Your browser stores these files to speed up websites. However, it can cause some problems in QuickBooks Online (QBO) when they become outdated. Clearing those out is super easy and takes just a second. 

In the meantime, let's start by accessing your account through an incognito window to rule out the possibility of a webpage issue. You can refer to these shortcut keys to open an incognito window in all supported browsers:

• Chrome: Ctrl+Shift+N
• Firefox: Ctrl+Shift+P
• Safari: Command+Shift+N

If it works, I recommend that you clear its cache. By doing this, you can remove that historical data and access QuickBooks with a clean slate. Alternatively, you can run QBO on another supported browser to see if it has something to do with your browser. 

If you're still getting the same message, you can disconnect your bank and reconnect it in QuickBooks. Alternatively, you can download an updated list of your transactions from your bank's website and upload them to QuickBooks using a CSV file. 

Visit me here again in the Community and post about your results after the troubleshooting. I'm determined to help you succeed.
