I'm trying to configure ArcGIS DataStore 10.9.1 installed on windows server 2019
with ArcGIS server Machine on Win2019. it is failed with error:
Could not connect to server on machine 'https:\\GISSERVERFQDN:6443'. ArcGIS Data Store or ArcGIS Server on that machine may not be running or the machine is not reachable at this time.
however, ArcGIS Server Machine is running and can connect to it on the browser.
