Hosting server grayed out unable to select Hosting server

[KennethBusby]

The following message is in a flyout when I put my cursor over the server. 

"The federated server uses a non-ArcGIS Data Store as the ArcGIS Server's Managed Database and cannot be set as a hosting server."

I have installed Arcgis Data Store and followed the instructions but it is not showing up. 

anyone have this issue?

Did you import your own certificate to use for port 6443? If so, can you describe how the certificate was created, (CN, who it's signed by, etc).

Hi Kenneth

Does your hosted ArcGIS server allow use admin URL via WebAdaptor URL? https://webdaptorURL/hostarcgis/manager

If yes and if you could un-federate it with Portal. Then federate it back with the Hosted ArcGIS server via WebAdaptor URL. You will able to see the drop-down list from the hosted ArcGIS server URL (This working for me for Enterprise 10.8.1). The valid SSL certificate is for hosted ArcGIS WebAdaptor SSL 

If you did not allow the hosted server to use the admin URL via WebAdaptor then you can do that via the portal admin page.. in the federated server (the hosted ArcGIS server one) and click update... then it will update it to the hosted server.
