I did exact thing as per this link https://oracle-base.com/articles/misc/configure-tcpip-with-ssl-and-tls-for-database-connections

But I am always getting the below error.

ORA-28864: SSL connection closed gracefully

I am using free version of 21C database

That's a fairly generic error - it's exceptionally tough for us to help you with this alone.

The article is based on 12.1.0.2; it's possible something has changed in the versions between.

Check the docs on configuring TLS:

https://docs.oracle.com/en/database/oracle/oracle-database/21/dbseg/configuring-secure-sockets-layer-authentication.html#GUID-63D92753-C1F3-4330-9944-F645B25630FD

If you're still stuck, this suggests:

Enable Oracle Net tracing and attempt the connection again to produce trace output. Then contact Oracle customer support with the trace output.
