When you run across a domain like p2p-sto2.discovery.steamserver.net, the first question is usually "is this safe to visit?" The short answer is that there's nothing to visit. This subdomain doesn't serve a working website — it returns a generic 404 error and rejects any attempt to make a secure connection.
From a safety standpoint, the biggest red flags are the complete lack of HTTPS encryption and the total anonymity of the owner. There is no WHOIS record, no contact page, about page, or any other way to identify who put this server online. Even basic legal pages like a privacy policy or terms of service are absent.
This domain appears to be a backend server endpoint rather than a consumer-facing website. But that doesn't make it safe to trust blindly. Without encryption or transparency, any data sent to this server could be intercepted, and there is no accountability if something goes wrong. If you encountered this link somewhere and are wondering whether it's a scam check, the safest assumption is to treat it as untrustworthy and avoid engaging with it entirely.
