I don't think it's a proxy problem. The importer is successfully reaching Facebook, but Facebook is telling the importer that Facebook is having an "internal server" problem. In other words, it looks like something is wrong at Facebook.
It could just have been a temporary issue. If it persists, I would suggest posting your question at http://socialnetimporter.codeplex.com/discussions. That's the home of the group that created the Facebook importer, and they might know more about what's wrong. (The importer is actually a "plug-in", and not part of NodeXL itself.)
