Ok, I have had a struggle now for a week, after my portal and arcgis server was having connection issues in 10.6 I decided I would upgrade to 10.7.1. After a few tries, I finally got Portal installed, registered the web adaptor for it "portal".
Now I am trying to complete the ArcGIS Server Setup Wizard. https://localhost:6443/arcgis/manager/ I go to Join Existing Site, this is after I have run Configure ArcGIS Server Utility also. and then i get the following error.
Failed to log in. Invalid username or password specified.
I have tried everything I can think of, my guy on my support ticket seems to be out of ideas as well, i have uninstalled Server and re-installed. Need help ASAP.
