Upon cloning an oracle instance, the connection to the Oracle server came back with an error

Ora-12514: Invalid Connection TNS Listener not currently know of service requested in connect descriptor

  • The listener was listening on the right port
  • Firewalls were off and client to ping server

I did change the Mac Address of the server when cloning, 

In the end I recloned and left the Mac Address’ as is and this seem to fix the issue
