I have an application built in the Web AppBuilder that uses a service secured in AGS but the map is not secured in AGOL so the credentials are not saved. When I deployed the app to our web server instead of prompting me for credentials it just shows the loading gif. After contacting esri support I installed their proxy and changed the server url to my server. While I can now get the credentials prompt to come up I get a 403 when I try to sign in. The message being returned is "Proxy is being used for an unsupported service: https://gis.baycountyfl.gov/arcgis/tokens/". How do I need to alter the proxy config give me a token?
