Thanks for taking the time to reach out to the Community for support, @Healthyway. I'll lay down a few steps to help you fix the error you encountered while setting up a new connection for Chase Bank into QuickBooks Online. 

Error 572 results from Oauth (an open standard for authentication) connection with Chase Bank. I've got some methods below to resolve this. 

First, we can start a manual download to update your connected bank account so you can have the latest available transactions. Here's how: 

1. Go to Banking from the left navigational pane.
2. Choose your bank.
3. Click Update.

If downloads seem slow, the issue may be on your bank's end. You'll want to sign in to your bank's website by selecting Link Account from the Banking page. Search for your bank and, copy the URL, then sign in. If you're unable to do so, there may be a major issue. You'll want to check the following: 

1. Check your account for messages, notifications, or alerts.
2. Look for any display issues as you navigate the website. These can block QuickBooks from downloading new transactions.
3. Check your bank's website for any announcements about new security requirements.

Once done, you can proceed to Step 3 in this article: What to do if you get a bank error or can't download transactions in QuickBooks Online.

For future reference, check out this guide if you can't find your downloaded transactions: What to do if you can't find downloaded transactions in QuickBooks Online.
