SQL Developer Connection to Oracle XE 18c

User_EYE0AJun 11 2021

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
