Cant repro this issue, looks like an issue specific to your environment. Possible that you might have a corporate firewall or proxy or something that might be causing this, we sign all releases , major and nightly builds. Maybe try this in a different machine or environment ? Possible that validation might be stale in your end , not sure.
