Meaning

Timeouts differ from "unreachable": nobody answered. Check whether ICMP is filtered by a firewall or cloud security group, and test the real service port (Test-NetConnection host -Port 443, nc -vz) because many hosts block ping but run fine.

Common causes

  • Host down or unplugged
  • Firewall or security group blocks ICMP
  • Routing problem or packet loss en route
  • Wrong IP address
  • Rate limiting of ICMP

⚡ Quick fix

  1. Test the service port instead of ping
  2. Allow ICMP echo in the firewall/security group
  3. Compare with a ping to the default gateway

Detailed fix by platform

Windows

  1. powershell
    Test-NetConnection 203.0.113.10 -Port 443
ping -n 10 203.0.113.10

How to diagnose

  1. Gateway ping — Works?
  2. Port test — Open?
  3. ICMP — Allowed?
