Can't answer the question, but just a couple of points you may or may not be aware of. The centre 'horseshoe' lights up ONLY when you are connected so I wouldn't expect it to work if you are not connecting. And the 'backend' services are unlikely to be a problem as you are trying to view locally and not remotely (and no-one else is reporting a problem.
Have you reset the box ? If so and it didn't help have you done a factory reset ?
