Your corporate network uses a proxy server that blocks anonymous PowerShell traffic.

PowerShell 2.0 relies on .NET Framework 2.0 or 3.5, which predates modern TLS protocol versions. When you attempt to download from a server that requires , the connection fails because the older .NET framework does not support these protocols by default.

To overcome this, the admin had to add a secret incantation at the very beginning of their script to force PowerShell to use modern security protocols: powershell

PowerShell 2.0, originally released with Windows 7 and Windows Server 2008 R2, remains a significant presence in legacy enterprise environments. While modern versions of PowerShell (3.0 and above) introduced convenient cmdlets like Invoke-WebRequest (often aliased as wget or curl ), PowerShell 2.0 requires a different approach to download files from the internet.
The server had no modern tools, no web browser, and only installed. 🛑 The Digital Straitjacket Alex could not simply download a patch. Internet Explorer was locked down by group policies.
GitHub often returns a redirect. WebClient does not auto-follow redirects in all cases. Use this workaround: $webClient
Because Invoke-WebRequest tracks the download state natively, it provides an automatic progress bar and error handling, reducing the amount of manual .NET plumbing you have to write. Best Practices for Legacy Environments
Once upon a time in the world of Windows administration, circa 2009, a sysadmin faced a common but tricky task: they needed to download a file from a remote server using nothing but the command line. In those days, PowerShell 2.0
Server requires TLS 1.2 or 1.1, but PowerShell 2.0 defaults to SSL 3.0 or TLS 1.0. Fix: Add the TLS 1.2 line before creating the WebClient:
