Error 'Unable to verify Authentication Server's hostname and/or port' when installing v18.x and later client   
    Auth Error
                                                           

 

 

Cause:

 

 

Communication issue between client and NetWorker Authentication Server (typically run on the NMC server, which may be the same host as the NetWorker server) on port 9090.   
    If upgrading from v9.x or below, this port may not be open between firewalls as it was not required.
                                                           

 

 

Resolution:

 

 

Check if port 9090 is open between the client and NetWorker authentication Server, and the services are running on the server.
