How to Fix Chrome ‘Resolving Host’ Slow Loading

Understanding the ‘Resolving Host’ Issue in Chrome

Experiencing slow loading times in Chrome due to ‘Resolving Host’ issues can be frustrating. This problem often results from DNS server delays, causing Chrome to take longer than usual to resolve website addresses. Fortunately, there are several effective methods to fix the Chrome ‘resolving host’ slow loading problem.

Quick Fixes to Try First

• Restart your router to refresh your internet connection.
• Close and restart Chrome.
• Delete cached files: at the top right of Chrome, select More (three dots) > Delete browsing data.
• Disable any VPN connections that might be interfering with DNS resolution.

Changing to Faster DNS Servers

Switching to a faster DNS server can significantly reduce the time Chrome takes to resolve hostnames. Here’s how to change DNS settings across different platforms:

Windows

1. Press Windows + R, type ncpa.cpl, and press Enter.
2. Right-click on your active network connection and select Properties.
3. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
4. Choose Use the following DNS server addresses and enter the preferred DNS server addresses (e.g., Google DNS: 8.8.8.8 and 8.8.4.4).
5. Click OK to save changes.

macOS

1. Choose Apple menu > System Settings, then click Network in the sidebar.
2. Click your network service (Wi-Fi or Ethernet), click Details, then click DNS (Apple’s steps).
3. Click the + button below the DNS Servers list to add a server (e.g., Google DNS: 8.8.8.8, 8.8.4.4).
4. Click OK to save changes.

Linux

1. Most desktop distributions set DNS in the network settings of your connection. Use that first, because a network manager or DHCP client can rewrite /etc/resolv.conf.
2. If your system does use a hand-edited /etc/resolv.conf, add lines for your preferred DNS servers, such as Google’s: nameserver 8.8.8.8 and nameserver 8.8.4.4 (Google Public DNS setup).
3. Save the file and restart your network service.

Flushing DNS Cache

Flushing the DNS cache can clear outdated or corrupted DNS records, helping Chrome resolve hosts more efficiently.

Windows

1. Press Windows + R, type cmd, and press Enter.
2. In the command prompt, type ipconfig /flushdns and press Enter.
3. A confirmation message will appear once the DNS cache is flushed.

macOS

1. Open Terminal from Applications > Utilities.
2. Type the command sudo killall -HUP mDNSResponder and press Enter.
3. Enter your password if prompted and wait for the process to complete.

Linux

1. Open a terminal window.
2. On systems that use systemd-resolved, type sudo resolvectl flush-caches and press Enter.

Turning Off Page Preloading

To browse and search faster, Chrome preloads pages that you might visit. If you want to rule it out, you can turn it off (Google’s steps):

1. Open Chrome and go to chrome://settings/performance, or select More > Settings > Performance.
2. Turn off Preload pages.

Checking Hosts File

Incorrect entries in the hosts file can interfere with DNS resolution.

Windows

1. Navigate to C:\Windows\System32\drivers\etc.
2. Open the hosts file with Notepad run as administrator, so you can save it.
3. Look for any incorrect or suspicious entries and remove them.
4. Save the file and restart your computer.

macOS and Linux

1. Open a terminal window.
2. Type sudo nano /etc/hosts and press Enter.
3. Remove any incorrect or suspicious entries.
4. Press Ctrl + X, then Y, and Enter to save changes.

Conclusion

By following these steps, you should be able to resolve the slow loading issue caused by Chrome ‘resolving host’ problems. Whether it’s changing your DNS server, flushing the DNS cache, or adjusting settings in Chrome, each solution targets common causes of this issue. If problems persist, consider consulting the official Google Chrome Help Center for further assistance.
