Are you tired of seeing the frustrating “Cannot be reached” error every time you try to access a website? This issue can be a major obstacle for both website owners and visitors alike, leading to lost traffic, revenue, and productivity. But don’t worry, you’re in the right place! In this comprehensive guide, we’ll explore the common causes of the “Cannot be reached” error and provide step-by-step solutions to fix it.
Understanding the “Cannot be Reached” Error
Before we dive into the fixes, it’s essential to understand what causes this error in the first place. The “Cannot be reached” error, also known as the “ERR_NETWORK_CHANGED” error, occurs when your browser is unable to connect to a website’s server. This can happen due to a variety of reasons, including:
- Server issues
- DNS resolution failures
- Firewall or antivirus software blocking the connection
- Internet connectivity problems
- Browser cache and cookie issues
- Website maintenance or downtime
Basic Troubleshooting Steps
Before we get into more advanced solutions, let’s cover some basic troubleshooting steps to rule out common issues.
1. Check Your Internet Connection
Ensure You’re Connected to the Internet
The most obvious step might seem silly, but it’s essential to confirm that you’re connected to the internet. Check your Wi-Fi or Ethernet connection to ensure it’s stable and working properly. If you’re using a mobile device, try switching to a different network or restarting your device.
Verify Your Network Settings
Check your network settings to ensure that they’re configured correctly. Make sure your DNS server settings are correct, and you’re not using a proxy server. You can reset your network settings to their default values or contact your internet service provider for assistance.
2. Refresh and Retry
Simple Yet Effective
Sometimes, a simple page refresh can resolve the issue. Try hitting the refresh button (F5 or Ctrl+R) to reload the page. If that doesn’t work, try closing and reopening your browser or restarting your device.
Advanced Troubleshooting Steps
If the basic troubleshooting steps didn’t resolve the issue, it’s time to get a bit more advanced.
1. Check the Website’s Status
Is the Website Down?
Use online tools like Down for Everyone or Just Me or Is My Website Up to check if the website is down for everyone or just you. If the website is indeed down, you can try contacting the website owner or waiting for a few hours before trying again.
2. Clear Browser Cache and Cookies
Clean Slate
A cluttered browser cache and cookie store can cause connectivity issues. Clear your browser’s cache, cookies, and browsing history. You can do this by pressing Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac) and following the prompts.
3. Disable Firewall and Antivirus Software
Temporary Fix
Firewall or antivirus software might be blocking the connection to the website. Try temporarily disabling these programs to see if the issue resolves. Be cautious when doing this, as it may compromise your system’s security.
4. DNS Resolution Issues
DNS to the Rescue
DNS resolution issues can cause connectivity problems. Try using a public DNS service like Google Public DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1). You can do this by changing your DNS server settings in your network preferences.
5. Browser Extensions and Add-ons
The Culprit Behind the Scenes
Sometimes, a problematic browser extension or add-on can cause connectivity issues. Try disabling all extensions and add-ons, then re-enabling them one by one to identify the culprit. Remove any problematic extensions or add-ons.
Server-Side Solutions
If the above steps didn’t resolve the issue, it’s possible that the problem lies on the server-side. Here are some solutions for website owners:
1. Server Maintenance and Uptime
Keep Your Server Running Smoothly
Regular server maintenance, including software updates and security patches, can help prevent downtime and connectivity issues. Ensure your server is running the latest software and is configured correctly.
2. DNS Configuration
Proper DNS Configuration
Verify that your DNS configuration is correct and up-to-date. Check for any DNS propagation issues and ensure your domain is pointing to the correct IP address.
3. Firewall and Security Software
Configuring Firewall and Security Software
Ensure that your firewall and security software are configured correctly and not blocking legitimate traffic. Whitelist your website’s IP address and domain to prevent false positives.

The “Cannot be reached” error can be frustrating, but it’s often a solvable issue. By following the steps outlined in this article, you should be able to identify and fix the problem. Remember to check your internet connection, refresh and retry, and try advanced troubleshooting steps like clearing browser cache and cookies, disabling firewall and antivirus software, and resolving DNS resolution issues. If you’re a website owner, ensure your server is running smoothly, and your DNS configuration and firewall settings are correct. With patience and persistence, you’ll be able to overcome the “Cannot be reached” error and get back to browsing or running your website smoothly.
What is the “Cannot be Reached” error?
The “Cannot be Reached” error is a frustrating issue that can occur when trying to access a website, online service, or network resource. It is usually indicated by an error message stating that the website or resource cannot be reached, and may be accompanied by an error code or other technical details. This error can be caused by a variety of factors, including network connectivity issues, DNS resolution problems, and firewall or antivirus software blocking access.
The “Cannot be Reached” error can be particularly frustrating because it can be difficult to diagnose and resolve. In some cases, the error may be due to a problem on the website or resource side, in which case there may be little that can be done to resolve the issue. However, in many cases, the error can be resolved by troubleshooting and fixing issues on the user’s side.
What are the common causes of the “Cannot be Reached” error?
There are several common causes of the “Cannot be Reached” error, including network connectivity issues, DNS resolution problems, and firewall or antivirus software blocking access. Additionally, the error can also be caused by issues with the user’s internet service provider, problems with the website or resource itself, and conflicts with other software or system configurations. In some cases, the error may be due to a temporary glitch or outage, and may resolve itself over time.
To troubleshoot the error, it is helpful to try to identify the underlying cause. This can involve checking network connections, DNS settings, and firewall or antivirus software configurations. It may also be helpful to try accessing the website or resource from a different device or network to see if the issue is specific to the user’s current setup.
How do I troubleshoot the “Cannot be Reached” error?
To troubleshoot the “Cannot be Reached” error, start by checking the basics: make sure your network connection is stable and functioning properly, and that your device is configured correctly. Next, try checking the website or resource’s status page to see if there are any known outages or issues. You can also try resetting your DNS cache or flushing your DNS resolver to see if that resolves the issue.
If these basic troubleshooting steps do not resolve the issue, you may need to dig deeper. Try checking your firewall or antivirus software settings to see if they are blocking access to the website or resource. You can also try using a different browser or device to see if the issue is specific to your current setup. If none of these steps resolve the issue, you may need to seek further technical support or assistance.
What is DNS cache, and how do I reset it?
The DNS (Domain Name System) cache is a temporary storage of DNS records that are used to resolve domain names to IP addresses. The DNS cache is used to speed up the process of accessing websites and online resources, but it can sometimes become outdated or corrupted, leading to issues like the “Cannot be Reached” error. Resetting the DNS cache can help to resolve these issues by wiping out the outdated or corrupted records and allowing the DNS system to fetch fresh records.
To reset the DNS cache, you will need to use the command prompt or terminal on your device. The exact steps will vary depending on your operating system, but on Windows, you can use the command “ipconfig /flushdns” to reset the DNS cache. On Mac or Linux, you can use the command “sudo killall -HUP mDNSResponder” to achieve the same result.
Will restarting my router fix the “Cannot be Reached” error?
Restarting your router can sometimes resolve the “Cannot be Reached” error, particularly if the issue is related to a network connectivity problem. When you restart your router, it can help to reset the network connection and re-establish communication between your device and the internet. Additionally, restarting your router can also help to resolve issues with your internet service provider or other network-related problems.
However, restarting your router will not always resolve the “Cannot be Reached” error. If the issue is related to a problem with the website or resource itself, or if it is due to a firewall or antivirus software blocking access, restarting your router will not fix the issue. In these cases, further troubleshooting and troubleshooting may be necessary to resolve the error.
Can I use a VPN to fix the “Cannot be Reached” error?
In some cases, using a Virtual Private Network (VPN) can help to resolve the “Cannot be Reached” error. A VPN can help to bypass network connectivity issues or firewall or antivirus software blocking access by routing your internet traffic through a different server. This can be particularly helpful if you are trying to access a website or resource that is blocked or restricted in your location.
However, using a VPN is not a guaranteed solution to the “Cannot be Reached” error. If the issue is due to a problem with the website or resource itself, or if it is caused by a more complex technical issue, using a VPN may not resolve the problem. Additionally, using a VPN can also introduce additional technical issues or slow down your internet connection, so it should be used with caution.
When should I seek further technical support?
If you have tried the troubleshooting steps outlined above and are still unable to resolve the “Cannot be Reached” error, it may be time to seek further technical support. This can include contacting your internet service provider, reaching out to the website or resource’s technical support team, or seeking assistance from a professional IT or network administrator.
Additionally, if you are unsure of how to troubleshoot the error or are not comfortable with the technical aspects of resolving the issue, it may be helpful to seek further technical support. A qualified technical support team can help to diagnose and resolve the issue more quickly and efficiently, saving you time and frustration.
