This domain looks odd, but it's actually part of Google's video delivery network. The 'gvt1.com' suffix and 'gvs' server header point to a Google Video Server β the same infrastructure that powers YouTube. If you've ever watched a video buffer, you've connected to a similar server. There is no scam risk here; the 404 page you get is just because the root URL isn't meant to be a webpage. For anyone wondering 'is rr4---sn-jvhj5nu-qufs.gvt1.com fake?', the answer is no β it's a legitimate server endpoint. The security checks confirm it's clean and well-maintained. You don't need to do anything special; treat it like any other Google CDN address.
