The error code you encountered means that Bank of America Money Network is unable to connect to Mint due to either of the following: bank web site maintenance, high traffic volumes, or network connectivity issues. Your account/s for the bank/s involved are not going to show updated values as a result, but this should be temporary and may get fixed on it’s own.
I triggered a connection refresh on my end, but I recommend that you wait for at least 24 hours from the time that you last logged in before logging in again. Mint runs a daily batch update which fixes errors resulting from previous connectivity issues, and waiting for this to complete helps ensure our resolution.
To complete the fix after 24 hours:
1. Login to your Mint account and click on the "Accounts" link at the top of the page.
2. Look for the Bank of America Money Network.
3. Click either the "Refresh/Update" or "Fix It" button (if you click the “Fix It” button, you'll be prompted to re-enter your log in credentials for the financial institution).
People come to Mint for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:
Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
