Err_Address_Unreachable Error is one of the most common types of Chrome errors and generally happens due to DNS (Domain Name Servers) issues. This then leads to a broader error named Site Can’t be Reached, by preventing the browser from loading the web page.

DNS loads the web pages from the host (the one where web pages are stored in the cloud).

Also, if you have slow internet connectivity or due to some other issues, your browser may show up an error and may not be able to connect to the host.

The problem can occur even if you have a very good internet connection.

If you are getting the err_address_unreachable error on your Chrome web browser upon visiting a certain website, then this is the result of an error in the Domain Name System (DNS),

The error in this DNS can be due to a number of reasons like:

• A Router with improper functioning or old ones can submit the requests to the inappropriate ports.
• Faulty proxy setting can also be the reason for this issue, emerging the issue by interfering with your computer’s request.
• Accessing a private page on a public network.
• Your internet server is not connected to the proper ports and hence cannot handle the server request.

The issue may be in general resolved by a simple reboot if the issue is minor, but in many cases, you may need to perform some operations in order to bring Chrome back to its normal state.

Depending on the possible reason behind the error, here are the potential fixes to it.

Restart Your Router

Turn off the power supply of the router and wait for 5 minutes. It is advisable to restart your system, too, while the router is restarting. Then turn it on and connect your computer to the internet after at least 3 minutes. Try accessing the website and check if the error message has disappeared.

Disable Proxy Server

It is ideal to use a proxy server, similar to a VPN, when you connect to a public network. However, it could interfere and cause network issues if you are using a proxy server outside your organization or office, as it changes how your device connects to the internet.

To fix err_address_unreachable, either disable or enable the proxy server by following the instructions below.

•  Invoke the Run window (WIN+R), input “inetcpl.cpl” in the search box and press Enter to open Internet Properties.
• Switch to the Connections tab. Then click LAN settings under the Local Area Network (LAN) settings section.
• In the pop-up window, uncheck Use a proxy server for your LAN and click OK to save the changes you have made.

To enable proxy server, you need to check “Use a proxy server for your LAN”, the same place where you had unchecked the settings when disabling.

Now, open the Chrome browser and check if the error is solved.

Clear browsing data

Your cookies also possess the chance of being the culprit in such cases. If the data is corrupted, then clearing the browsing data might help.

Here are the steps to clear browsing data from Chrome browser:

1. Launch the Chrome browser.
2. Click on the menu icon (three dots) at the top right side of the browser screen.
3. From the options list, choose the Settings option.
4. On the settings option, go to the Security and Privacy section.
   
5. Under this section, head inside Clear browsing data.
6. Then, proceed into the Advanced tab.
7. Change Time range to All time and then check the following items:
   • Browsing history,
   • cookies and other site data,
   • Cached images and files
8. Finally, click on the Clear data button at the bottom and wait for the data to be cleared.
   

Clearing the data will take a relative amount of time, depending on the frequency of the previous clearing.

Clear Google Chrome DNS Cache

Another way you can try to fix the “err address unreachable” issue is to flush Chrome’s DNS cache.

• Launch Google Chrome.
• Input chrome://net-internals/#dns in the address bar and press Enter.
• Click the Clear host cache button.

After clearing the cache on Chrome, open the website again and check if it works properly.

Disable Your Antivirus Application

Your antivirus protects your computer from viruses, but sometimes antivirus blocks some websites, and that can cause the err_address_unrachable error. Disable your antivirus software temporarily, and if the problem is fixed, replace the antivirus with another one, or adjust the strictness of the antivirus.

Reset TCP/IP

If all the solutions above fail to fix err address unreachable issue, you can try resetting TCP/IP with Command Prompt.

• Open Run window. Then type cmd and press Shift + Ctrl + Enter to run Command Prompt as administrator.
• Input the following commands one by one and press Enter after each.
• ipconfig /release
• ipconfig /all
• ipconfig /flushdns
• ipconfig /renew
• netsh int ip set dns
• netsh Winsock reset

Next is to exit the Command Prompt and restart your computer. When the PC is on, launch Google Chrome and check if the issue is solved.

Check the Address you are visiting

There are chances that you are trying to visit a private address by connecting to a public network.

• Trying to access the setup page of your router connection when connected to your smartphone’s Wi-Fi, you won’t be able to access that page while being on a public connection like the hotspot of your phone.
•  Always check the address you are trying to access if it is accessible via a public network or not.

Remove Chrome Extension or Try Incognito

Open the error generating Web Page in the incognito mode of Chrome Browser.

If the page opens securely in private mode, a Chrome extension is causing the error.

 Just go to; chrome://extensions and uncheck all the extensions manually to find the culprit. Then, turn off the extension.

“Forget” the Wi-Fi network and reconnect to it again

Another option you can try is to remove the Wi-Fi network from your device’s saved Wi-Fi passwords list, i.e., “forget” the network, and reconnect to it.

To “forget” the network, follow the steps below:

1. Go to Settings and tap on Wi-Fi;

Tap on the Wi-Fi network you want to forget and tap on the Settings icon beside the connected Wi-Fi name. This will pop up a menu with the “forget connection” option.

After you have “forgotten” the network, reconnect to it, with or without your passwords, and check if the connection is resolved.

Try Another Wi-Fi Network

A simpler solution to give a shot is to connect to a different Wi-Fi network. If you’re getting errors due to your router or ISP, this will give you an answer.

After connecting to another network, if your device’s internet connection works fine, and you can access websites without error, your device is working properly, and you need to change the WI-FI network.

Turn on and turn off the airplane mode

Turning on and off the airplane mode will restart the device’s WI-FI and mobile data. The network connectivity will be resolved if the issue was lying within the components.

Conclusion

ERR_ADDRESS_UNREACHABLE may show up on your screen while you are using the Chrome browser. It could be due to some issues in your connection, and you can fix it within the Chrome browser. Sometimes, you may need to disable or enable the proxy to fix this error. Also, make sure to check if the page is running on any other Device or Browser.

Suppose all of the above solutions don’t work for you. In that case, you can contact your internet service provider and ask them for a solution. If they can’t solve your problem, then change your ISP provider.
