Did you add columns to the list in SharePoint, and then the extract stopped working? If so, does the list start working again if you remove those columns?
I don't have a quick answer for you, since I've been researching SP -> Tableau interaction myself recently. Not a lot of docs on it, especially on the SharePoint side.
I will say this -- take your OData link (for SP 2010 it looks like https://sharepoint..../sites/.../listdata.svc/, it may be something else for 2013) and plug that directly into a Chrome browser. If Chrome shows you a fully-formed, no-error XML (assuming you are using the listdata.svc) of the entire list, then the SharePoint is probably working normally.
If the last line ends with something like "An error occurred while processing this request," then you've probably got some kind of invalid column or characters on the SharePoint side. What exactly those might be, I don't know.
Internet Explorer doesn't like to show mal-formed XML feeds, so I just use Chrome for this kind of test.
