We're still investigating possible solutions on our end that may assist players who are receiving Error 3007 when attempting to patch 1.0.6a. We'll provide more updates as they become available in this thread.
Until this issue is resolved, you can still try to use different DNS servers, and Narull has provided an excellent workaround for that process here. Please note that this workaround may not be successful for you.
Thank you to everyone who has reported the issue or provided tracerts to assist our investigation. :)
