ERR_ADDRESS_UNREACHABLE: What It Means and How to Fix It
Appears on: Chrome, Edge. ERR_ADDRESS_UNREACHABLE means your computer cannot find a route to the destination IP. The most common cause is a misconfigured network adapter, a bad gateway, or a firewall blocking the route.
What ERR_ADDRESS_UNREACHABLE actually means
The operating system tried to route a packet to the target IP address and found no valid route — the IP is unreachable from your current network configuration. This is a network routing problem, not a DNS problem (the address was resolved, but a path to it does not exist).
Most likely causes (ranked)
- Your default gateway is incorrect or unreachable
- A VPN changed the routing table and left it corrupted after disconnecting
- The network adapter is misconfigured with the wrong subnet or gateway
- A firewall is blocking outbound traffic to the destination subnet
- The target IP is a private address that is not reachable from the internet
How to fix ERR_ADDRESS_UNREACHABLE
Step 1: Check your default gateway
On Windows: run 'ipconfig' and confirm the Default Gateway is your router's IP (usually 192.168.1.1 or 10.0.0.1). On macOS: System Settings → Network → details. If the gateway is missing or wrong, set it to your router's IP.
Step 2: Restart after VPN disconnect
If this error appeared after disconnecting a VPN, the VPN left routing table entries behind. Restart your computer to restore the original routing table, or run 'route delete 0.0.0.0' in an admin Command Prompt.
Step 3: Reset the network stack
Run 'netsh int ip reset' and 'netsh winsock reset' as admin on Windows, then reboot. This clears corrupt routing configuration accumulated over time.
Step 4: Check your firewall rules
Temporarily disable Windows Defender Firewall or your third-party firewall and retry. If the error disappears, a custom outbound rule is blocking the route.
Step 5: Release and renew IP address
Run 'ipconfig /release' then 'ipconfig /renew'. This forces DHCP to re-assign a correct IP, subnet mask, and gateway from the router.
Still not fixed? Rule out your connection
If the steps above did not clear the error, the next step is verifying the underlying internet connection is healthy. Run a speed test — if download, upload, and ping come back normal, the error is specific to one site or browser state. If the speed test also fails or shows packet loss, the problem is at the network or ISP layer.
Frequently Asked Questions
Is ERR_ADDRESS_UNREACHABLE always a local problem?
Almost always yes — it is a routing issue on your device or local network, not a website or ISP problem. The exception is IPv6-only addresses, which may be unreachable if your ISP does not support IPv6.
Why does ERR_ADDRESS_UNREACHABLE appear after using a VPN?
VPNs modify the system routing table to tunnel all traffic through the VPN server. When the VPN disconnects unexpectedly (crash or manual disconnect), these routing entries can persist incorrectly, blocking normal routing. A system restart or manual route deletion fixes this.
