Used sdkman to install several packages (had to set proxy and proxy-user in .curlrc to negotiate the corporate proxy). When I tried installing grails and groovyserv they both fail with curl Received HTTP code 403 from proxy after CONNECT.

I think I'm negotiating the proxy OK (because the other installs worked), so does this indicate that there is something different at the end server giving me the grails content, or is my proxy objecting to the grails content.

Any advice on how to debug / fix would be appreciated

Windows XP, cygwin (very recent download), Corporate proxy
