Server's log looks like this:
javax.servlet.ServletException: javax.servlet.ServletException: javax.servlet.ServletException: javax.servlet.ServletException: com.esri.arcgis.discovery.admin.rest.ResourceNotFoundException: Could not find resource or operation 'Locator_v02.GeocodeServer' on the system
It seems that the .sd file was issued a few days ago, so it doesn't seem to be a problem with the version of the Server and the locator creation tool. The version of Server is 10.9.
