"Error switching license manager!"

Following Quick Start for ArcGIS Pro pdf -> Concurrent Use. 


  • Converted ArcGIS Pro Named User Lic successfully. 
  • We have already established an ArcGIS Lic Manager for our existing ArcMap/Globe/Scene/Catalog concurrent installations. 
  • Authorized ArcGIS Pro Advanced successfully, our Lic Server Admin shows availability 1 of 1. 
  • But now, after installing ArcGIS Pro and selecting Configure your Lic Options -> Concurrent Use Lic -> when inserting our established Lic Manager we see "Error switching License Manager!" // Invalid Host Name


FQDN and IP does not work.  It's strange that our other Arc concurrent-use products work just fine...
