[FIX] Cloudflare ‘Error 523: Origin is Unreachable’

Cloudflare is a popular content delivery network (CDN) that helps improve website performance, security, and reliability. However, like any other technology, it is not immune to errors. One of the common errors faced by website owners using Cloudflare is the ‘Error 523: Origin is Unreachable.’ This error occurs when Cloudflare is unable to establish a connection with the origin server, resulting in a temporary unavailability of the website.

If you have encountered this error while browsing a website, don’t worry, as there are a few steps you can follow to resolve it.

1. Check the website status

The first step to fixing this error is to check if the website is actually down or if it’s just a temporary issue. You can use tools like DownDetector or IsItDownRightNow to check the status of the website. If the website is down, then the error is most likely caused by an issue with the origin server. In this case, you can’t do much except wait for the website to be back up.

2. Check the origin server connection

In some cases, the error can be caused due to an issue with the connection between Cloudflare and the origin server. To verify this, you can try accessing the website directly by using the IP address instead of the domain name. If you are able to access the website using the IP address, then the issue is with the DNS settings or the origin server’s configuration.

3. Review DNS settings

Cloudflare acts as a proxy between the visitor and the origin server. So, it is important to ensure that the DNS settings are correctly configured to point to the correct IP address for the origin server. You can check this by comparing the IP address in the DNS settings with the one provided by your hosting provider. If there is a difference, you can update the DNS settings in your Cloudflare account.

4. Check the origin server’s configuration

If the DNS settings are correct, then the issue could be with the configuration of the origin server. Make sure that the server is listening on the correct port and that there are no firewall issues blocking the connection. You can also try restarting the origin server to see if it resolves the issue.

5. Disable Cloudflare temporarily

In some cases, the Cloudflare security features like WAF (Web Application Firewall) or rate-limiting rules can cause the ‘Error 523: Origin is Unreachable’ to occur. To troubleshoot this, you can temporarily disable Cloudflare by changing the DNS records back to direct mode. If the website is accessible after disabling Cloudflare, then you can tweak the security settings to resolve the issue.

6. Contact Cloudflare support

If none of the above steps work, then you can reach out to Cloudflare support for assistance. They have a team of experts who can help you troubleshoot the issue and get your website back online.

In conclusion, the ‘Error 523: Origin is Unreachable’ on Cloudflare can be caused due to various reasons. By following the above steps, you can easily identify and fix the underlying issue. Cloudflare also has a comprehensive knowledge base and community forum where you can find more information and solutions for common errors.

Method 2: Changing the Default DNS

Method 2: Changing the Default DNS

One of the most common ways to increase your internet speed is by changing the default DNS (Domain Name System) settings. DNS acts as the phonebook of the internet, translating domain names into IP addresses so that your browser can load the desired website. By changing the default DNS settings, you can potentially improve your browsing and download speeds.

Here are the steps to change the default DNS on your computer or mobile device:

Step 1: Find the current DNS settings
Before you can change the DNS settings, you need to know what your current settings are. On a Windows computer, you can open the Command Prompt and type “ipconfig /all” and press Enter. Look for the “DNS Servers” line to find your current DNS settings. On a Mac, go to System Preferences > Network > Advanced > DNS tab to view your current settings. On a mobile device, go to Settings > Wi-Fi > Click the “i” next to your Wi-Fi network name > DNS to view your current settings.

Step 2: Choose a new DNS provider
The most popular and trusted DNS providers include Google (primary DNS: 8.8.8.8, secondary: 8.8.4.4), OpenDNS (primary DNS: 208.67.222.222, secondary: 208.67.220.220), and Cloudflare (primary DNS: 1.1.1.1, secondary: 1.0.0.1). You can also use an online tool like DNS Benchmark to find the fastest and most reliable DNS provider for your location.

Step 3: Change the DNS settings
Once you have chosen a new DNS provider, go back to your network settings and click on the option to manually change the DNS settings. Depending on your device, the process may vary. For example, on a Windows computer, you can go to Control Panel > Network and Internet > Network and Sharing Center > Change Adapter Settings > Right-click on your network connection > Properties > Internet Protocol Version 4 > Properties > Use the following DNS server addresses > enter the primary and secondary DNS numbers. On a mobile device, you can simply click on the DNS field and enter the new numbers.

Step 4: Save and test the new DNS settings
Once you have entered the new DNS numbers, click on “Save” and wait for the changes to take effect. You can then test your new DNS settings by running a speed test or browsing websites to see if there is any noticeable improvement in speed.

Keep in mind that changing the DNS settings may not always result in a significant speed boost for your internet connection. However, it can improve your browsing experience and increase the overall performance of your network. You can also try using different DNS providers to find the one that best suits your needs.

Method 3: Disable / Uninstall 3rd party Firewall

If you’re experiencing issues with your computer’s internet connection or accessing specific websites, it may be due to a third-party firewall installed on your system. While firewalls are essential for protecting your system from online threats, they can also sometimes cause problems.

In this blog post, we’ll discuss how to disable or uninstall a third-party firewall to troubleshoot any connectivity issues you may be facing.

Step 1: Identify the Firewall Program

The first step is to identify the firewall program installed on your system. Look for names like Norton, McAfee, Comodo, ZoneAlarm, etc., in your list of installed programs. If you’re not sure which firewall you have, you can open the program and check the name or search online for popular third-party firewall programs.

Step 2: Disable the Firewall Temporarily

Once you have identified the firewall program, try disabling it temporarily. In most cases, firewalls have options to turn off their protection for a short period. This will help determine if the firewall is causing the issue or not.

To turn off the firewall, open the program and look for an option to disable or turn off the firewall. If you can’t find it, you can also try right-clicking on its system tray icon and selecting the disable option. Once the firewall is disabled, try accessing the websites or applications that were giving you trouble.

Step 3: Uninstall the Firewall

If disabling the firewall didn’t resolve the issue, it may be necessary to uninstall it completely. To do this, open the Control Panel and navigate to ‘Programs and Features.’ Here, you’ll find a list of all the programs installed on your system. Look for the firewall program and select it, then click on the uninstall option.

Follow the instructions to complete the uninstallation process. Once it’s done, restart your computer, and check if the issue has been resolved.

Step 4: Use Windows Defender Firewall

If you don’t want to use a third-party firewall, you can always rely on the built-in Windows Defender Firewall. It’s enabled by default and provides adequate protection for your system. To ensure it’s working correctly, open the Control Panel, and navigate to ‘System and Security’ > ‘Windows Defender Firewall.’ Here, you can check the settings and customize them according to your needs.

Step 5: Consider other Firewall Alternatives

If you want to continue using a third-party firewall, but it’s causing too many issues, you can consider switching to a different program. There are plenty of firewall alternatives available, such as TinyWall, GlassWire, and ZoneAlarm Free Firewall, to name a few.

Final Thoughts

In this blog post, we discussed how to troubleshoot connectivity issues caused by a third-party firewall. We recommend trying to disable the firewall temporarily first, and if that doesn’t work, then uninstalling it completely. If you still want to use a firewall, you can switch to a different program or rely on the built-in Windows Defender Firewall. We hope this guide was helpful in resolving your firewall-related issues.
