Hello @janandar
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with your Bank of America accounts. I'm wondering here if we might be able to connect in a test file. This should give us a better idea of what exactly could be causing the issue. I'll leave steps down below and you can find it on the third step of the article.

Note: When selecting Bank of America you'll want to select advanced options and change the connection type to direct connect.
Once you get a chance to try these steps, please let us know what you find. From there we'll better understand our next steps/options.
Thanks,
Quicken Francisco
