How to configure Chocolatey to use a corporate proxy?

Question

I'm having trouble installing Chocolatey packages from behind a corporate proxy. Internet Explorer is correctly configured but I'm having issues getting it to work through Powershell.

I can use the Web-Client to download pages e.g. Microsoft.com, but ultimately Chocolatey fails to download packages with the prompt "Please provide proxy credentials:" which will not accept my domain login as being valid. Sometimes I just get the error "Exception calling "DownloadFile" with "2" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."

I have two machines - one of them can download the packages fine, and the other gives the errors above, but they both show Direct access (as below):

PS C:\Windows\system32> netsh winhttp import proxy source=ie

Current WinHTTP proxy settings:

    Direct access (no proxy server).

PS C:\Windows\system32> netsh winhttp show proxy

Current WinHTTP proxy settings:

    Direct access (no proxy server).

I'm not too sure what is happening here. Any suggestions?

Chocolatey has proxy instructions at https://github.com/chocolatey/choco/wiki/Proxy-Settings-for-Chocolatey and specifically the section on explicit proxy. Ensure you have the proper version of choco installed for that to work. If that is incorrect, we should fix the documentation/choco to make it correct.

For posterity:

Explicit Proxy Settings

Chocolatey has explicit proxy support starting with 0.9.9.9.

You can simply configure 1 or 3 settings and Chocolatey will use a proxy server. proxy is required and is the location and port of the proxy server. proxyUser and proxyPassword are optional. The values for user/password are only used for credentials when both are present.

choco config set proxy <locationandport>
choco config set proxyUser <username>
choco config set proxyPassword <passwordThatGetsEncryptedInFile>

Example

Running the following commands in 0.9.9.9:

choco config set proxy http://localhost:8888
choco config set proxyUser bob
choco config set proxyPassword 123Sup#rSecur3
