Chrome ERR_ADDRESS_UNREACHABLE — Server Cannot Be Reached

Errorchrome errors

Overview

Chrome ERR_ADDRESS_UNREACHABLE indicates the browser cannot establish a network connection to the server's IP address.

Key Details

  • DNS resolution succeeded but the IP address is not reachable
  • Different from ERR_NAME_NOT_RESOLVED (DNS failure)
  • Can indicate the server is down, IP is wrong, or network path is broken
  • Common with sites that recently changed hosting providers
  • Also appears when trying to reach internal/private IP addresses from external networks

Common Causes

  • The website's server is completely down
  • DNS cache returning a stale/wrong IP address
  • Firewall blocking outbound connections to that IP range
  • The website moved to a new IP but DNS TTL has not expired
  • Network routing issue between your ISP and the hosting provider

Steps

  1. 1Check if the site is down for everyone: use downdetector.com or isitdown.site
  2. 2Flush DNS cache: chrome://net-internals/#dns > Clear host cache
  3. 3Also flush OS DNS: ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac)
  4. 4Try accessing by IP directly (if known) to bypass DNS
  5. 5Disable VPN or proxy if active and retry
