Hi there, I am trying to setup new oracle environment. I downloaded Oracle 21C -XE. In SQL-Plus, I am able to connect using "sys as sysdba" with its password, but when I am trying to create new connection in SQL Developer, its throwing me this error: ora-1017 invalid username/password logon denied.
I am trying to find a solution from past couple of hours. Can you please assist on this issue??? This will be really helpful. Thanks,

[@wilsonoxilus2730]
