While configuring Web adaptor 11.3, I get: HTTP Error 404

I have installed and licensed these on a single EC2 instance in the order given:

1. Arcgis server
2. Arcgis Datastore
   1. Validate it with the server
3. Arcgis portal

Upon installation of the ArcGIS web adaptor, I created one for the server. Upon configuration, I clicked on the first option for the server. Upon clicking next I get the error:

HTTP Error 404. The requested resource is not found.

Hey @AhmedRauf 

If this is a Windows machine, I would ensure that the IIS web server is running, in order to use the web adaptor this will need to be routed through the IIS. You may try to uninstall the web adaptor, restart the hosting machine, and reinstall the web adaptor to be sure that everything came across correctly.
