What Causes “This Site Can’t Be Reached” and ERR_ADDRESS_UNREACHABLE?

This error message from Google Chrome — like so many other error messages — is pretty ambiguous. It doesn’t point you lớn a specific problem, and it can have numerous causes. Unfortunately, that means solving the problem usually involves the kitchen sink approach — basically, try things until something works. We can narrow it down a bit, however.

How khổng lồ Isolate the Cause of the Problem

You should try connecting khổng lồ the website, or websites, over a different network. If you have a cellphone, turn off your phone’s Wi-Fi và try connecting over cellular data. If it doesn’t work, the odds are extremely good that the problem is not your device or network. You can also plug the address into IsItDownRightNow và see if others are reporting the same problem.

If it does work, however, it means that the problem is probably on your end, not the website’s. We can narrow things down a bit further by checking to lớn see if every device on the network is affected, or just one. Use another device, lượt thích an extra computer, laptop, phone, or tablet, & see if they also can’t connect. If all devices are affected, then your problem is with your modem or router. Scroll down lớn the sub-section titled “If All Devices Are Affected” for some possible solutions.

If only one device is affected, you’re stuck with the kitchen sink approach.

How lớn Fix “This Site Can’t Be Reached” If All Devices Are Affected

There are only three likely explanations if every device on your network is affected.

Your internet Service Provider (ISP) is experiencing problemsYour router is experiencing problemsYour modem is experiencing problems

The first possibility— a problem with your ISP — is not something you can fix. If you know one of your neighbors has the same service provider you can ask them if they’re experiencing an outage too. If they are, you’ll have khổng lồ wait until the problem is fixed.


Modems & routers, like all computers, are capable of experiencing glitches. Restart both your modem & router by unplugging them for a minimum of 30 seconds. If you want to lớn be absolutely sure, leave them unplugged for a few minutes, và then plug them back in.

If you’re thinking “Wait! I don’t have a modem and router, I just have this one thing my ISP sent me,” don’t worry. That is probably a unit that combines the modem và router into one device — they’re extremely common now. Just unplug it for a few minutes & then plug it back in.

Give your modem & router (or combined unit) about five minutes to lớn start up again, then try connecting lớn the website(s) with which you had problems. If it doesn’t work, you’ll need to lớn try some other troubleshooting steps.

Check Your Cables và Connections

Warning: Be sure that you do not excessively bend or yank any cables or connections while you’re checking things out. They’re not super fragile, but they’re not usually designed lớn take a beating, either.

A damaged Ethernet, coaxial (coax), or fiber optic line can also cause “This Site Can’t Be Reached” errors, though it would probably be evident that your mạng internet is totally disconnected. Go to lớn your modem, router, or combined unit & give the cables an inspection visually and with your hands.

If you have a separate modem & router, you’ll probably have one cable coming into the modem and another one connecting the modem lớn the router. A combined unit will have one cable coming in from the outside, & then as many Ethernet cables going out as you have hardwired devices. Make sure that none of the connectors are damaged or loose, và that all of the connectors are firmly seated in their sockets.

There shouldn’t be any sharp bends or kinks in the cables that you can see or feel. This is especially important if you have a fiber optic line coming directly into your trang chủ — the copper conductors found in coax and Ethernet cables are generally a lot more forgiving than the glass or plastic fibers found in fiber optic cables.

The insulation on the outside of the cable should be smooth & undamaged. Surface scuffing and scratches are fine, but deep cuts, torn, or chewed insulation could mean that cable — và the twisted pairs inside — have been severely damaged. Also be on the lookout for areas where the insulation is whiter than the surrounding insulation — this can indicate that the cable was bent lớn an extreme angle or pinched, & then bent back into shape.

Factory Reset Your Modem và Router

If restarting your modem và router didn’t fix the issue, and you can’t find any physical problems, the last thing you can try is a complete factory reset. Resetting your modem và router to lớn the factory settings will probably fix any software bugs that might be causing connection problems, but it’ll also wipe out any personalized settings you have, like Wi-Fi network names and passwords.

Go to your modem, router, or combined unit và look at the back of the device. The factory reset button is usually small & recessed into the body of the device so it can’t be accidentally pushed. Grab a paperclip — the most useful tool for nerds — and bend it straight. Then push the reset button & hold it for a minimum of 10 seconds. Some devices require as long as 30 seconds to trigger a factory reset, and you won’t bởi vì any harm holding the button down longer than necessary. Vị this for both the modem và router if you have separate units.

Once it resets it’ll take a few minutes for everything to initialize, so just be patient.

If Only One Device Is Affected

Unluckily, there are more troubleshooting options for an individual device than there are if all of your devices are impacted. So here it is: everything và the kitchen sink.

Restart Your Device

The first thing you should try is a full restart. Restarting your computer can solve a whole range of issues, và is the easiest possible solution. The user interface (UI) changes between versions of Windows, so restarting Windows 10 is a bit different from restarting Windows 11, but the general process is the same.

Click “Start,” then click the nguồn icon, then click “Restart.”

Wait for the restart to complete, & then try connecting again.

Google Chrome Issues

Browsers have gotten better with time, but no software is perfect. There are plenty of ways a browser’s own settings or cache can prevent it from working properly.

The first thing to bởi is clear your history, cookies, & cache, then restart Google Chrome và try connecting again.

A clean installation of Google Chrome could help as well. Just make sure to lớn back up any important passwords or bookmarks, just in case.

Computer Network Settings

A problem with your PC’s DNS settings, DNS Cache, Dynamic Host Configuration Protocol (DHCP), Winsock, or the TCP/IP Stack settings could be responsible for the error, and there is no way lớn guarantee the automated Network Troubleshooter will fix them. Here’s how you can try to fix them manually.

Launch Command Prompt as Administrator. If you prefer, PowerShell or Windows Terminal will work too.

You can bởi these steps one at a time to try & isolate the problem, or you can just go right down the list and try them all at once. Ideally, you should vày them one at a time. It is possible that the connection error occurred because of something you did, và knowing the source of the problem might allow you lớn prevent it in the future.

Note: All of the following commands should be run in an elevated Command Prompt, PowerShell, or Windows Terminal. After they are, you should try connecting again.

Click the Start button, type “Command Prompt” into the tìm kiếm bar, and then click “Run as Administrator.”


Reset (Flush) DNS Cache

Your PC’s DNS Cache should be reset every time your computer restarts, since it is stored in RAM — which is volatile memory — and not on your hard drive. The DNS cache can be corrupted by accident by a bug or problem with the DNS vps you use, or it could have been poisoned deliberately. You can reset the DNS cache manually with a command.

Type or paste ipconfig /flushdns into Command Prompt.


If it worked correctly, you should see the message “Successfully flushed the DNS Resolver Cache” in the window.

Reset DHCP Assignment

Dynamic Host Configuration Protocol — more commonly referred to as DHCP — is how your router assigns your device a local IP address. Every device on your local network is assigned an IP address so your router can keep track of what mạng internet (or LAN) traffic needs to go khổng lồ each device.

This is probably not the origin of your issue, especially if only one website is affected. However, at least a handful of people have reportedly solved the “This Site Can’t Be Reached” error by releasing và renewing their local IP address.

Type the following commands into an elevated Command Prompt one at a time:

ipconfig /releaseipconfig /renewCommand Prompt will display a ton of information that will flash by pretty quickly — as long as you don’t see any error messages like “Cannot renew IP address,” it worked. Try connecting lớn the mạng internet again and see if the error is still there.

Reset TCP/IP Stack

The TCP/IP Stack is critical in determining how information is routed on the internet. Each computer maintains its own TCP/IP settings. You can manually edit them via RegEdit if you wanted to, but in this case, resetting them to mặc định should be enough khổng lồ fix any problems that have occurred.

Open an elevated Command Prompt và type the following command:

netsh int ip reset

You will see a danh mục of items that have been reset, followed by: “Restart the computer lớn complete this action.”


Restart your computer, and then see if Google Chrome is still reporting an error.

Reset Winsock

Winsock is an application programming interface (API) present in Windows that lets different components of Windows’ network software communicate, lượt thích the TCP/IP stack and your browser.

Resetting Winsock can resolve some connection problems. Winsock issues often result from malware or an improperly uninstalled program that made changes khổng lồ the Windows Winsock Catalog.

Type netsh reset winsock into an elevated Command Prompt, và then restart your computer. After the restart, try connecting khổng lồ the website or websites that were giving you the “This site can’t be reached” error.

Follow the Instructions for “If All Devices Are Affected”

If only one device is affected, certain issues — lượt thích a damaged line coming in khổng lồ your house — can be ruled out entirely. However, there are plenty of issues, lượt thích a router configuration error or a problem with a connection, that could affect only one device.

If you’ve gone through all of those steps and are still experiencing difficulty with Chrome, you should try disabling Windows Firewall & completely uninstall any Virtual Private Network software (VPNs) you might have on your computer.
