We've filed a ticket in our ticketing system regarding this issue, and the developers are currently looking into it. This also flags your message as someone who is having this issue, so we'll respond here if we have any updates.
For the time being, the best way to get your transactions into Moneydance is to use a web browser to download files from your bank's web site.
We'd recommend you download using the OFX or QFX file format if available. If not, use the QIF file format. (These files are sometimes referred to as Quicken or MS Money files). You can import the files to Moneydance using File --> Import.
Thank you for your patience and sorry for the inconvenience.

Our lead developer was able to make contact with Citi's tech people, who should have implemented a change today to allow Moneydance to connect again. For most people this seems to work without further setup, but you may have to recreate your connection if it still doesn't work.
