Getting an error code when trying to connect American Express business credit card account. I’ve tried a number of times on mobile/web. Is there a fix?

We recognize the importance of connecting your Amex account to QuickBooks Online (QBO), clayc213, and we're committed to providing you with the necessary guidance and support to facilitate a quick and seamless connection process.

To start off, let's investigate whether this error issue is related to your bank. We'll log in to your bank's website and examine if there are any ongoing maintenance activities or notifications that require your attention. These factors can sometimes impact the process of connecting your bank account.

1. Get first the URL QuickBooks uses to connect.
2. Go to Banking.
3. Select Link account. 
4. Reminder: You don't need to add an account, you just need the listed URL.
5. In the search box, find your bank and click it.
6. Copy the URL for your bank.
7. Sign in to your bank or credit card's website using the copied URL.

After successfully logging in, it's a good sign that the issue is likely not significant. Now, let's proceed with checking the following items:

1. Check if there are messages, notifications, or alerts in your account.
2. Find out if there are display issues as you navigate the website. This prevents QuickBooks from connecting your bank account.
3. Check if there are announcements about new security requirements on your bank's website.
4. If everything looks good, go back to QuickBooks. Then reconnect again your American Express Business credit card account.
