SQL Developer Connection to Oracle XE 18c

User_EYE0A

The SQL Developer shows the following error message after testing the connection to the Oracel XE 18c database.

Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection (CONNECTION_ID=oN8etyzVSyCgYUJpNd+efA==)

parameter:

• user: sys with correct password
• hostname, port and SID is aligned with tnsnames.ora and listener.ora
• Listener is started: LSNRCTL start

Any idea why this IO Error comes up?

Thanks
