Fixing Error Code 105 ERR_NAME_NOT_RESOLVED in Google Chrome on Windows 10
If you suddenly receive an error saying, “Error 105 (net:: ERR NAME NOT RESOLVED): Unable to resolve the server’s DNS address” when browsing the web, then this means that the DNS lookup has failed. This kind of error is one of the most commons one you can encounter while using the Chrome browser. And since it’s a pretty common error, the solutions for this one are pretty easy as well.
Option 1 – Disable both the Antivirus and Firewall temporarily
There are times when antivirus programs and the firewall blocks a website which they consider to be malicious or even because of false-positive effects. Thus, you need to disable these programs temporarily as it might be the reason why you’re getting the “Error 105 (net:: ERR NAME NOT RESOLVED): Unable to resolve the server’s DNS address” error in Chrome.
Option 2 – Check the Network Cables and restart the router then reconnect
Of course, the next thing you have to do is to check if the network cables connected to your computer or router are properly connected. And if your computer is connected via Wi-Fi, you need to make sure to restart your router once. In addition, you can also forget the Wi-Fi your computer is currently connected to and then try reconnecting again to see if it would work.
Option 3 – Try running the Chrome Cleanup tool
You might want to run Google Chrome’s built-in Malware Scanner & Cleanup tool as it could also help in getting rid of any unwanted ads, pop-ups and even malware, as well as unusual startup pages, toolbars, and anything else that might overtake the network and could affect the performance of the browser.
Option 4 – Try removing the Proxy
Removing the Proxy might also help you in fixing the ERR_NAME_NOT_RESOLVED error in Chrome. Here’s how you can do it:
- Tap the Win + R keys to open the Run dialog box.
- Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
- After that, go to the Connections tab and select the LAN settings.
- From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
- Now click the OK and the Apply buttons.
- Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.
Option 5 – Disable Prefetch in Chrome
In case you don’t know, Google makes use of a prediction service that helps users in completing searches and typing URLs in the address bar. This prediction service uses the already resolve IP address to connect to the website you’ve already visited. Thus, it would be better if you disable it in cases like this one.
- Open Chrome’s Settings.
- Next, go to Privacy and Security then look for “Prefetch”.
- After finding Prefetch, toggle off the “Use a prediction service to help complete searches and URLs typed in the address bar” setting and then restart Chrome.
Option 6 – Flush the DNS, reset Winsock and then reset TCP/IP
- Click the Start button and type in “command prompt” in the field.
- From the search results that appear, right click on Command Prompt and select the “Run as administrator” option.
- After opening Command Prompt, you have to type each one of the commands listed below. Just make sure that after you type each command, you hit Enter
- ipconfig /release
- ipconfig /all
- ipconfig /flushdns
- ipconfig /renew
- netsh int ip set dns
- netsh winsock reset
After you key in the commands listed above, the DNS cache will be flushed and the Winsock, as well as the TCP/IP, will reset.
Option 7 – Try using the Google Public DNS
- The first thing you have to do is right click on the network icon in the Taskbar and select Network and Sharing Center.
- Next, click on the “Change Adapter Settings” option.
- After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
- Right click on your network connection and click on Properties.
- Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
- After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
- Type in “8.8.8” and “220.127.116.11” and click OK and exit.
Option 8 – Reset Chrome
Resetting Chrome can also help you fix the error. Resetting Chrome means restoring its default settings, disabling all the extensions, add-ons and themes. Aside from that, the content settings will be reset as well and the cookies, cache and site data will also be deleted. To reset Chrome, here’s what you have to do:
- Open Google Chrome, then tap the Alt + F keys.
- After that, click on Settings.
- Next, scroll down until you see the Advanced option, once you see it, click on it.
- After clicking the Advanced option, go to the “Restore and clean up the option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
