Windows Server 2012 Update Error 80072EFD

Question

Hi,

We have Windows Server 2012 R2 running an application server.
the server stopped updating and the error is 80072EFD.

We had enabled proxy settings to block internet and allowed access only to Authorized sites.
Below registry path contains ProxyOverride key that consists URLs as mentioned below.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyOverride

www.google.com;www.idealake.com;<local>;windowsupdate.microsoft.com;.windowsupdate.microsoft.com;.update.microsoft.com;.windowsupdate.com;.download.windowsupdate.com;wustat.windows.com;ntservicepack.microsoft.com;go.microsoft.com

Any solution please?

Thanks and regards

Hi.
Error 80072EFD may mean that a program running on your computer is preventing Windows Update Services (SVCHOST) from accessing the Internet. This program includes firewalls, antispyware, Internet security or antivirus programs, and proxy servers.
Have you tried the following troubleshooting?

• Clean boot.
• Test with different users.
• Disable Windows Firewall.

If the above troubleshooting ideas don't work, I looked up the relevant information，you might need to add the Windows Update website addresses to the blocking program's exceptions or "allow" list or allow Windows Update Service to connect to the Internet through port 80 and port 443.

Meanwhile, you can try renaming the following folders:

• c:\Windows\System32\Software Distribution
• c:\Windwos\System32\Catroot2

Check that the following services have been started and configured as "Automatic"（Win+R>services.msc）
Background Intelligent Transfer Service
Windows Update
Cryptographic service

Hope the information is helpful.
