Skyiot-uw23.srv.ygles.com is a subdomain that currently returns a 404 error and displays no useful content. That alone makes it difficult to assess β there's no business to evaluate, no contact information, and no clue what the domain was intended for. The technical setup is mixed: it has a valid SSL certificate and loads quickly, but it also accepts older, less secure TLS versions and lacks basic security headers. Most legitimate services that use a subdomain for APIs or internal tools still have some public-facing information like an about page or documentation. Here, there's nothing. If you came across this URL from an email or ad, treat it as an unknown β there's not enough evidence to call it a scam, but also no reason to assume it's safe. Without a clear purpose or owner, the smart move is to steer clear.
