However, as of today this is simply hitting a 404 error and I can't seem to find a possible work around. I understand Yahoo has made some changes to Yahoo finance and their other APIs. Does anyone have a potential solution?
According tothis Answer, Yahoo changed part of the protocol of their API. That Answer includes a link to a bug report where you can apply a workaround for Datafeed Toolbox. Since it sounds like you are directly trying to access Yahoo via a URL rather than using Datafeed Toolbox, a little searching suggests to me that you want to try https:// instead ofhttp://. If that doesn't work you may want to contact Yahoo directly to ask how to update the URL you are using.
