Yes, that did the trick, thank you very much! 
For future reference, for the lost wanderer, if you are behind an HTTP proxy, you have to:
- Edit the file
runtime/conf/net.propertiesunder the Designer Launcher installation directory, and set this parameters:
java.net.useSystemProxies=true
http.proxyHost=<proxy_ip>
http.proxyPort=<proxy_port>
https.proxyHost=<proxy_ip>
https.proxyPort=<proxy_port>
This will allow the Launcher to detect the Ignition gateway. Check if you have to exclude some IP of the local network, e.g. for development server.
- Inside the Designer Launcher, go into
Settings => Designer Defaults, and set theJVM Argumentsbox with this:
-Dhttps.proxyHost=<proxy_ip>;-Dhttps.proxyPort=<proxy_port>;-Djava.net.preferIPv4Stack=true;-Dignition.chromium.switch.proxy-server=<proxy_ip>:<proxy_port>;
If you don’t have HTTPS enabled on your Ignition server (but why?), than you have to add also this:
-Dhttp.proxyHost=<proxy_ip>;-Dhttp.proxyPort=<proxy_port>;
This will allow the Designer itself to correctly communicate with the gateway. You can also change the settings in a single gateway entry, if you need so.
