Quick Answer: ERR_ADDRESS_UNREACHABLE means your Chromebook’s network stack couldn’t find a valid route to the server’s IP address at all, a step earlier in the process than a timeout or a refused connection. It’s most often caused by a misconfigured network setting, a VPN routing conflict, or a temporary problem with your router rather than the website itself.
What Causes This Error
- A misconfigured static IP, gateway, or subnet setting on the Chromebook
- A VPN client creating a conflicting or broken routing table entry
- The router itself failing to route traffic to the wider internet
- IPv6 connectivity issues on networks with incomplete IPv6 support
- A firewall rule blocking the specific destination address entirely
How to Fix It
Step 1: Reload and test another site
Try a well-known site like google.com. If every site fails the same way, the issue is your network configuration, not one destination.
Step 2: Check for a manually set static IP
Go to Settings > Network > Wi-Fi > (your network) > Network and confirm the IP address, gateway, and subnet are set to Automatic (DHCP) rather than a manual static configuration, unless you specifically set one up and know it’s correct.
Step 3: Disable any active VPN
VPN clients sometimes install a routing table entry that conflicts with your normal network path. Disconnect the VPN and reload the page to see if it resolves immediately.
Step 4: Switch to a public DNS server
Go to Settings > Network > Wi-Fi > (your network) > Network > Name servers and switch to Google (8.8.8.8) or Cloudflare (1.1.1.1). See our DNS settings guide for full steps.
Step 5: Restart your router
Power cycle it for 30 seconds. A router with a corrupted routing table can produce this exact error across multiple destinations at once.
Step 6: Try a different network
Connect to a phone hotspot briefly. If sites load normally there, the fault is in your home network’s routing, not the Chromebook itself.
Still Not Fixed?
If ERR_ADDRESS_UNREACHABLE happens on every site across every network you try, including a phone hotspot, this points to a deeper Chromebook network stack issue rather than any single router. Try clearing your DNS cache and confirming ERR_INTERNET_DISCONNECTED isn’t the more accurate description of what you’re seeing.
FAQ
Is this the same as ERR_INTERNET_DISCONNECTED?
No. ERR_INTERNET_DISCONNECTED means there’s no internet connection at all, while ERR_ADDRESS_UNREACHABLE means a connection exists but no valid route to that specific address could be found.
Can a VPN really cause this error?
Yes, this is one of the more common causes. A VPN app that doesn’t clean up its routing table properly after disconnecting can leave stale routes that block normal traffic.
Does this mean the website is down?
Not necessarily. It usually points to a routing problem on your end rather than the site’s server being offline, testing the same site on a different network quickly confirms which side the fault is on.
