Thank you for reaching out here in the Community, @daniel-dlcarpent.
Let's get this error fixed so you can connect your bank account to QuickBooks Online (QBO).
Before we start, can you please verify the name of your bank? This way, we can further check the status of your bank's connection.
Error 572 is a result of an OAuth (an open standard for authentication) connection with your bank. Many banks are switching to a new connection service called OAuth. And we're also switching to OAuth to make online banking even better.
Since this is the first time you tried to connect your bank account, you'll need to coordinate with your bank to allow this new connection. Then, connect it again to your QBO account.
You might want to learn more about categorising and matching your bank transactions. Here's an article you can read for more guidance: Categorise and match online bank transactions in QuickBooks Online.

There can be a lot of possible reasons why you encounter QuickBooks bank feed error 572. Following are a few of them:
That being said, I suggest verifying with your bank institution if they have ongoing maintenance in their system. Once verified bank website is working well and has no ongoing maintenance. I recommend reaching out to our customer support team to help you validate what causes of this error message you've encountered.
On the other hand, you can manually upload transactions into QuickBooks Online to get the most recent one.
I will be happy to hear any updates from you. I like to ensure you can work with your bank connection in QuickBooks. Take care, and have a great day!
