We have an issue while using the storymap after downloading and configuring in an application.
It is asking every time login credentials even we set the proxy in the server at App -> Config.js.
Please suggest to resolve the issue.
Environment: Portal for ArcGIS 10.5.1 with federated ArcGIS Server
we change the config.js here at below code snippet
// Edit those to set a custom sharing or proxy URL
// You have to edit those only if your webmap is deployed on Portal for ArcGIS instance and if you are not deploying the template on the Portal webserver
// If you are using ArcGIS Online or deploying the template on a Portal instance, you don't have to edit those URL
