I'm trying to set up Grails at my computer at work running Windows 10 and I'm unable to do so. I've downloaded the latest version from the website (3.3.8), added a GRAILS_HOME variable to my account pointing to the unzipped Grails directory and added the path to its bin subdirectory to the system Path and while grails -v works and outputs the version of Grails, Gradle and Java correctly, basically no other command does.
When I try to create some sample app with grails create-app someApp, I get | Error Error initializing classpath: services.gradle.org and a trace like this:
| Resolving Dependencies. Please wait...

Similarly, when I try to download a project (like the one generated from start.grails.org) and just run it locally with grailsw run-app, I get:

Even a simple help command doesn't work cause grails -help outputs | Error Error occurred running Grails CLI: repo.grails.org
What may be the reason for this? Is the corporate firewall blocking something? How may I make this work?
