It basically is a checks for connectivity to the resources you need for Flutter Development. You need to check your connection if it is an issue during running flutter doctor.

By doing a little bit of digging we can also find the actual file in flutter code for http host validation: https://github.com/flutter/flutter/blob/eb1a851f5843efb6cecab020467a2ffea48fd1d3/packages/flutter_tools/lib/src/http_host_validator.dart
