Getting Invalid token error when trying to access ArcGIS World Geocoding Service on non-public Web Map

[gytradzevicius]

Created Web AppBuilder application with Screening and Search widgets who use Geocoder URL: https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer WAB application hosted on IIS. Application Web Map secured (non-public). IIS and ArcGIS Portal are on different machines.

Screening and Search widgets do not work on the WAB application hosted on IIS. Invalid token error 498 received: https:///DotNet/proxy.ashx?https:///portal/sharing/rest/portals/self?token=eZEUhPFBh3K_ZJNp9PojslFuR_vuBeKJYPqgRXPL0de8B7l5id7ls5Gm0cY87RjHq6gqzeM51K4GdXasNaHRNcbegdOLbdowt51zrDvDmQkKG_79nMyxDmMM6TjU0VriHlVdm40JfdSbVW5bbjRevRwdt_VVoK_O8AIwHtRsm5s.?f=json

DotNet proxy.config:

<?xml version="1.0" encoding="utf-8" ?>
<ProxyConfig allowedReferers="*"
             mustMatch="true" xmlns="proxy.xsd">
    <serverUrls>
        <serverUrl url="https://<Portal_machine>"
                   matchAll="true"/>
    </serverUrls>
</ProxyConfig>

Hosted WAB application config.json proxy parameters:

    "httpProxy": {
        "useProxy": true,
        "url": "https://<IIS_machine>/DotNet/proxy.ashx",
        "alwaysUseProxy": false,
        "rules": [
            {
                "urlPrefix": "https://<Portal_machine>",
                "proxyUrl": "https://<IIS_machine>/DotNet/proxy.ashx"
            }
        ]
    }

I already contacted ESRI technical support but this scenario is not further investigated because is not directly WebApp builder related. Thanks.
