PROBLEM
Attempting to log in to ArcGIS StoryMaps from Portal for ArcGIS fails, with the login page constantly looping, preventing the ArcGIS StoryMaps main page from loading. This issue occurs when navigating to ArcGIS StoryMaps from the Portal for ArcGIS app launcher, and from the Create StoryMaps option on the Portal for ArcGIS Content page.
No error message is displayed in the log files.
There is an additional forward slash ('/') in the WebContextURL and privatePortalURL parameters in Portal for ArcGIS. This forward slash is added to the ArcGIS StoryMaps config.json file, and prevents logging in to the ArcGIS StoryMaps main page.
Below is an example of the incorrect WebContextURL and privatePortalURL parameters, with an additional forward slash at the end of the URLs.
{"WebContextURL":"https://machine_name.domain/arcgis/", "privatePortalURL":"https://machine_name.domain/arcgis/"}
Below is an example of the correct WebContextURL and privatePortalURL parameters.
{"WebContextURL":"https://machine_name.domain/arcgis", "privatePortalURL" :"https://machine_name.domain/arcgis"}
Remove the additional forward slash ('/') from the WebContextURL and privatePortalURL parameters, and ensure the forward slash is not present in the ArcGIS StoryMaps config.json file.
Note: Clicking Update Properties restarts Portal for ArcGIS. This process may take a few minutes.

Launch ArcGIS StoryMaps from Portal for ArcGIS. The app launches successfully and logs in correctly.
