Banking

Thanks for joining this conversation, @Paying Customer.

The error message you're getting indicates an issue with your financial institution which is the Discover Credit Card. You'll want to reach out to your bank and verify if there are conducting system maintenance at the moment.

Since performing the rebuild and verifying data utilities were unable to fix the issue, I highly recommend giving our Customer Care Support. They'll be able to do a screen-sharing session and see what's going on on your end when accessing the bank feeds center. They can also perform other troubleshooting steps if necessary. 
 

Here's how:

1. Open QuickBooks.
2. Go to Help, then select QuickBooks Desktop Help.
3. Select Contact Us.
4. Give a brief description of your issue, then select Let's talk, and then choose a way to connect.

Just in case, I'm also adding these articles for future reference:

• Deactivate Bank Feeds for an account.
• Resolve data damage on your company file.
• Top data damage errors in QuickBooks Desktop.

I'm always around to lend a hand if you have more questions about QuickBooks or any bank-related concerns. Just tag my name in the comment section so I can assist you further. Take care and have a good one.
