I am unable to get Powershell Core 6.1.0 on Linux to access a proxy successfully. Our corporate proxy utilizes IP based authentication and not user based.
So when I attempt to Invoke-WebRequest a bad URL, it will return the HTML of the proxy server rejecting the URL. When I attempt to iwr a genuine allowed URL (one, for example, I am able to browse from firefox on my Ubuntu server).
This is all an attempt to download modules from Powershell Gallery, again browsable from the VM, but cannot access the gallery from powershell even though it knows to use the proxy.
I get a common error on Invoke-WebRequests of 'No such device or address'.
