I am curious if you had any answers to this question?  I use BoA also and typically download and import manually, but it is not working.  Curious and assuming it may be a related and similiar issue.

I am having exactly the same issue. Quickbooks Pro Desktop.

Bank of America no longer allows you to download QBO files.

When I attempt to set up syncing with Quickbooks Pro Desktop, I get the "Sorry, we've run into a problem. QuickBooks is having trouble connecting to Bank of America - New. Options; Try again later, this is a temporary issue and will be resolved in a day or two."  But I have tried this numerous times over the past several weeks with exactly the same results. 

This is NOT a temporary issue. This appears to be a permanent failure and I suspect the failure originates in Quickbooks.

Good afternoon, @hughcan. 

Thanks for chiming in on this thread. We hate to hear that you've been having this experience with Bank of America in QuickBooks Desktop. 

To escalate the issue, I recommend contacting our Customer Support Team. They'll be able to review your account and see why this is occurring. Here's how: 

1. Go to the Help menu.
2. Press the QuickBooks Desktop Help/Contact us option.
3. Enter your question.
4. Tap Get a callback.

Please reach back out and let us know how the call goes. We want to ensure that you get this taken care of as soon as possible. Take care! 

Your instructions were completely incorrect. When you request a callback from support - using the functions of Quickbooks Desktop Pro - you get connected to a QB Online tech who knows nothing at all about Desktop Pro.

That person gave me a phone number to call. I called and that connected me to a worthless AI agent that could not understand the simplest requests or responses. By repeating the words "agent technical support representative" about ten times, I got the AI bot transfer me to a person.

The person was competent but could not resolve the issue. We did a screensharing session and I demonstrated that an attempt to make a direct connection to Bank of America. The error that appears is the same one I have always seen (going back months now). See screenshot. 

In the screensharing session, we also looked at the "Participating Financial Institutions" list - accessed from the Banking menu in Desktop Pro. Both the "Bank of America - New" and "Bank of America - QB Webconnect" listings within the Quickbooks Desktop product report that the supported download method is "Web Connect". However, Bank of America does NOT repeat NOT provide QBO files. It only provides the following file types:

Web connect for Quicken 2018 and above
Quicken and Managing Your Money - QIF file (2 digit)

Quicken - QIF file (4 digit)

Microsoft Excel format

Printable text format

These are the only options from Bank of America. 

So, the Quickbooks Desktop product SAYS it can connect to Bank of America using QB Webconnect, but it CANNOT because BofA does NOT provide QB Webconnect files (QBO files). The bank used to provide QBO files but that stopped about two months ago. 

At the very least, Intuit should update the information within the product itself show correct information about Bank of America connections. Ideally, Intuit will work with BofA to get the connection going again. BofA is only one of the five largest banks in the world. This should work.

Found this on Reddit:

Apparently BofA and Intuit don't communicate effectively at all, which is ridiculous since they must have millions of customers in common. Makes me want to stop using Intuit products completely.
