After Show-WindowsDeveloperLicenseRegistration in powershell, I get the following alert:

Show-WindowsDeveloperLicenseRegistration : Exception from HRESULT: 0x8024401B

I am using Microsoft Visual Studio Community 2015, Windows 8.1 Pro 64-bit, Windows is activated.Windows8.1-KB2913270-x64 is already installed on my pc.Proxy is properly set which I have verified using netsh winhttp show proxy.

P.S> This isn't a duplicate question. None of the solutions to similar problems has worked for me.

Thanks to @magicandre1981 to help me solve the error.

Short answer: Use open internet to avoid/solve any internet access related issues while getting developer license for windows 8.1.

Long answer:

If behind any proxy verify if the proxy is set properly using netsh winhttp show proxy.

I got error 0x8024401B while trying to get developers license for windows 8.1. This error occurred because there was some issue for internet access for windows machines from the lab I was working. This issue was solved after I accessed internet from outside the lab.

Further there was 0x80072f00 error. I was still behind a proxy server.
