Problem running on windows with embedded ES output

I'm trying to run logstash 1.5 with embedded ES, but I keep getting an error during startup:

{:timestamp=>"2015-06-02T15:55:02.275000+0200", :message=>"The 'embedded => true' setting is enabled. This is not recommended for production use!!!", :level=>:warn}

This is the relevant part of my config:

output {
    elasticsearch {
        embedded => true
    }
}

Any ideas what could be wrong?

Turned out to be a VPN issue. When disabling the active VPN connection, it worked.

Nilsga, vpn was the issue for me. Thanks!
