Hi @GTA ,   If your Cloudera Enterprise Trial has not ended yet, then the enterprise features should be there and that includes Navigator.   Could you please check if the trial license expired? If not, please provide some more information about the issue then. For example, what do you see when you try to access Navigator home page? What are the Navigator instances installed where you can find out from Cloudera Manager UI? Some screenshots may help out here. Also, if you see any error messages, it will help to share that error with log files (CM server log, Navigator metadata server log etc).    Thanks, Li ... View more
