Thank you for contacting us.
We've been looking into this issue and it seems all customers are encountering 400 and 500 errors - 404, 502 or 504.
A Yahoo support representative has confirmed that Yahoo Finance API has been discontinued.
From the changes that have been made, it seems like Yahoo is trying to prevent people from automated downloading like Moneydance (and so many others) are doing.
Our lead developer has mentioned that we may be able to make a change, that means the Moneydance connection will pose as a browser, rather than a program. This may allow the connection. However, it seems very likely that this will turn into a 'cat-and-mouse' game.
The current workaround is to download the quotes in a cvs file and import them by navigating to Tools > Securities > Edit then Import.
We are looking into other services we can use instead to resume the automatic downloads.
