In order to fix this error, we will be checking out the following fixes-

1. Set up Automatically Detect the connection settings.
2. Flush the DNS Settings.
3. Use a VPN Connection.
4. Clear Browser Data.
5. Remove conflicting Browser Extensions.
6. Reset Google Chrome Browser.

1] Set up Automatically Detect the connection settings

Start by typing in Internet Options in the Cortana Search Box. Click on the appropriate result.

Now navigate to the tab called Connections.

Under the section labeled as Local Area Network (LAN) settings. Click on the button that says LAN Settings.

Under the section of Proxy Server, uncheck the option that is labeled as Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections).

Click on OK and then Reboot the computer for the changes to take effect.

2] Flush the DNS Settings

You can Flush the Chrome DNS cache and check if that fixes your issues.

3] Use a VPN Connection

The network that your computer is logged on, might have blocked your access to that website. So, in order to overcome that, you can try these VPN Connection extensions from the Google Chrome extension web store and check if you can access the website normally.

4] Clear Browser Data

There are high chances that some browser data is conflicting with the website’s loading. This might be a very basic fix, but in this case, it can be proved to be highly reliable.

To do this, open Google Chrome and press the CTRL + H key combination on your keyboard.

This will open a new panel to delete your browsing history and other data.

Select every checkbox that you see and finally click on Clear browsing data.

Restart your browser and check if your error is fixed or not.

5] Remove conflicting Browser Extensions

There is a high chance that the extensions and toolbars installed on your browser are conflicting with your website’s loading. So, to fix that, you need to remove or disable these extensions and toolbars.

6] Reset Google Chrome Browser

You can reset Chrome browser settings to default and see if this helps. This will return your Google Chrome browser to its default state, which is as good as a fresh install.
