How is HTTP Host Availability in flutter 2.10?

Issue

When I run flutter doctor -v in Flutter stable version 2.10.1, I get this check:

[!] HTTP Host Availability
    ✗ HTTP host https://maven.google.com/ is not reachable. Reason: An error
      occurred while checking the HTTP host: Operation timed out

What should I do?
