Connection errors

ERR_ADDRESS_UNREACHABLE

There is no network path to the website server.

Quick answer

The server address was found, but your network has no route to it. This often happens with private addresses, broken network settings or provider routing problems.

When to wait: If a provider routing problem is the cause, it is usually fixed by them.

If you are visiting the website

  1. Check whether the address is internal Addresses that start with 192.168., 10. or 172.16. to 172.31., and names like router.local, only work inside one home or company network. From outside that network they are unreachable by design.
  2. Try another network Switch from Wi-Fi to mobile data, or the other way round. If the site works there, your network or internet provider may be involved.
  3. Check your VPN Some company sites only work while the company VPN is connected. Other VPNs can block local or certain routes. Reconnect the VPN, or turn it off once to test, then back on.
  4. Restart your connection A fresh connection gets new network settings from your router.
    Windows
    Open Command Prompt and run ipconfig /release, then ipconfig /renew. Or turn Wi-Fi off and on from the taskbar.
    macOS
    Click the Wi-Fi icon in the menu bar, turn Wi-Fi off, wait ten seconds and turn it on again.
    Android
    Turn Airplane mode on, wait about ten seconds, then turn it off again.
    iPhone and iPad (iOS)
    Turn Airplane mode on in Control Center, wait about ten seconds, then turn it off again.
  5. Restart your router Turn your router off, wait about 30 seconds and turn it on again. This renews your connection and its routes.
  6. Reset network settings as a last resort Only if nothing else helps and many sites fail. This deletes saved Wi-Fi passwords and VPN setups, so have them ready.
    Windows
    Settings > Network & internet > Advanced network settings > Network reset. You may need to set up VPN software again afterwards.
    Android
    Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth.
    iPhone and iPad (iOS)
    Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.

If you run the website

  1. Check DNS records Make sure public A and AAAA records point to public addresses, not internal ones. Check with dig example.com A +short and dig example.com AAAA +short.
  2. Check the IPv6 record If you publish an AAAA record (IPv6 address) but the server has no working IPv6, some visitors cannot reach you. Fix IPv6 or remove the record.
  3. Ask for a route trace Ask your host for an MTR or traceroute (a list of every network hop) between the server and an affected visitor. It shows where packets stop.
  4. Check your hosting provider's status Your host may have a known network outage. Their status page or support can confirm it.

Is it the website or me?

If the link points to an internal address, the website is only meant for one network, and nothing is broken. If it is a normal public site that fails only on your network, check your router and VPN.

If the site fails on every network you try, the problem is probably at the site's host or in its DNS records.

What this error is not

It is not a refused connection: no server ever got your request. It is not a DNS failure either, because the name was turned into an address.

The browser simply found no road to that address. Think of a correct house number on a street that is closed off.

For developers: what happens technically

Chromium uses error -109 when the operating system reports no route to the host or network. Often a router along the way answers that the destination cannot be reached.

Common triggers are internal addresses in public DNS, missing routes in VPN setups and broken IPv6 paths.

Common questions

What is a private or internal address?

It is an address that only exists inside one network, like your home or office. Your router uses one, often starting with 192.168. Nobody outside that network can reach it.

Why does the site work at the office but not at home?

The site is probably internal to the company network. You usually need the company VPN to reach it from home; ask your IT team.

Does this error mean I was blocked?

No. A block usually shows a refusal or a block page. This error means your network found no path to the address at all.

Likely causes

  • Sometimes The site uses an address that only works inside a certain network. (Website side)
  • Sometimes A router or VPN setting sends the traffic nowhere. (Your side)
  • Rare A routing problem at an internet provider. (Either side)
