If it does not work, try the following steps.
Reset the proxy list (and bypass list)
===============================
This issue can occur if the proxy has not been configured correctly. Let's
first reset the proxy list.
1. Open Internet Explorer.
2. On the Tools menu, click Internet Options.
3. Click the Connections tab, click LAN Settings, and then click Advance.
4. Delete any entry in the Exceptions section.
5. Quit Internet Explorer.
6. Click Start, click Run, type cmd, and then click OK.
7. Type the following commands. Press ENTER after each command.
proxycfg -u
proxycfg -d
net stop wuauserv
net start wuauserv
Delete the Hosts file
=====================
The Hosts file is used for host name resolution. If this file has been
modified, we cannot access the Windows Update site properly and can receive
the error code.
1. Click Start, Run, type "%SystemRoot%\system32\drivers\etc" (Without the
quotation) and then press Enter.
2. Right-click the hosts file and choose Delete.
3. Click Yes to confirm the deletion.
4. Then, clear the DNS (Domain Name Resolution) cache:
1). Click Start, Run, type "cmd" (Without the quotation) and press Enter.
2). In the opened window, type: "ipconfig /flushdns" (Without quotations)
and press Enter.
Note: The hosts file will be generated automatically after being removed.
