setting up Android SDK - get the "Failed to fetch URL http://dl-ssl.google.com/android/repository/repository.xml" error no matter what

Question

In trying to set up the Android SDK, I can't seem to get connected to the repository. With the proxy set correctly, and https forced to http, I get this error:

Failed to fetch URL http://dl-ssl.google.com/android/repository/repository.xml, reason: Connection reset.

Without the proxy set, I get the same result, except it says the connection has timed out.

Anything I'm missing here?
