After installing ArcGIS Server and Arcgis Portal, I am trying to configure the web adaptor to use it with portal but when I navigate this url: https://localhost/arcgis/webadaptor/portal , I have error 404 or a white page without any message.
Arcgis Server is 10.5
Arcgis Portal is 10.5
Arcgis Web adaptor is 10.5
OS is Windows 10
I am using web adaptor with IIS.
How can I solve this? Is there a bug with the web adaptor??
Please help me!!
