Resolution
UK-ROI Geocoderrelies on TomTom web services. Most of the time this error means that tool cannot contactapi.tomtom.com.
So, in order to be able to use the tool, make sure to whitelistapi.tomtom.com at the firewall or proxy level.
If a proxy is involved, ensure that Alteryx Designer is configured to use it (menu Options, User Settings, Edit User Settings, bottom of tab Advanced). PAC (Proxy Auto Config) scriptare not supported by Alteryx Designer at the moment. One needs to replace the script by the actual proxy server URL in Windows Control Panel, Internet Options.
