An “err_address_unreachable” error in Google Chrome indicates that you can’t reach the site you want to visit. This error usually appears when you try to visit a non-existent site. But sometimes, you may see the error even when attempting to load a valid website.

In that case, your browser may be experiencing an issue where it can’t find the website. You can try rebooting your router, disabling your antivirus, and changing your DNS server to potentially fix the problem.

    Restart Your Router to Fix the err_address_unreachable Error

    Your router’s minor issues can sometimes cause huge problems, like the one you’re experiencing in Chrome. Unless you know your router’s issue, you can try rebooting your router and see if that fixes Chrome’s problem.

    A few routers offer the option to reboot the device from settings. If you have one, access your router’s settings page in your web browser, open the Maintenance tab, and choose Restart The Router.

    Turn Off Your Antivirus Program

    Your antivirus program may be blocking the website, so Chrome displays an “err_address_unreachable” error. If you think this is the case, turn off your antivirus protection for a moment and see if that resolves the problem.

    You can temporarily disable most antivirus programs’ protection by opening the program and selecting the turn off option.

    Fix err_address_unreachable by Disabling All Chrome Extensions

    Chrome offers several extensions so you can enhance your web browsing experience. However, sometimes, these extensions end up being the culprit. Your “err_address_unreachable” error could result from a malfunctioning extension in Chrome.

    In this case, turn off all your Chrome extensions and then see if you still get the above error message. If the error goes away, one or more of your extensions are likely the cause of the problem, and you’ll have to remove them to fix your browser.

    1. Launch Chrome and select the three dots > More tools > Extensions option.
    2. Disable all extensions you see on the page.

    Flush Your PC’s DNS Cache

    Chrome uses your PC’s DNS cache to resolve domain names to IP addresses. This requires your DNS cache to be fully functional. If that’s not the case, and your cache has a problem, that can cause various issues in Chrome, including “err_address_unreachable.”

    Luckily, you can fix that problem by deleting your DNS cache files. This doesn’t delete your browser history or any of your files. Instead, your PC rebuilds the cache over time as you access websites in your web browsers.

    1. Launch the Start menu on your PC and search for Command Prompt. Select the tool in the search results.
    2. Enter the following command in Command Prompt and press Enter: ipconfig /flushdns

    Clear Host Cache in Chrome

    Chrome stores its host cache, and it’s worth clearing this when you experience network issues in your browser. Again, your files or browsing history won’t be affected when you delete the cache.

    1. Launch Chrome, type the following in the address bar, and press Enter: chrome://net-internals/#dns
    2. Select the Clear host cache button.

    Change Your DNS Servers

    In addition to clearing your PC’s DNS cache, you can fix most network issues by changing your DNS servers to something more stable, like Google’s Public DNS.

    1. Launch Settings on your PC by pressing Windows + I keys together.
    2. Select Network & Internet > Change adapter options in Settings.
