SSL is not being used to secure our connection to MySQL on Ubuntu 16.04

I have followed this tutorial here "How To Configure SSL/TLS for MySQL on Ubuntu 16.04 " and "How To Set Up a Remote Database to Optimize Site Performance with MySQL on Ubuntu 16.04 ".

In the log below, the have_openssl and have_ssl variables read “YES”. Furthermore, the ssl_ca, ssl_cert, and ssl_key variables have been populated with the names of the relevant certificates that we generated: mysql> SHOW VARIABLES LIKE ‘%ssl%’; ±--------------±----------------+ | Variable_name | Value | ±--------------±----------------+ | have_openssl | YES | | have_ssl | YES | | ssl_ca | ca.pem | | ssl_capath | | | ssl_cert | server-cert.pem | | ssl_cipher | | | ssl_crl | | | ssl_crlpath | | | ssl_key | server-key.pem | ±--------------±----------------+ 9 rows in set (0.01 sec)

However, when I check the connection details again, the specific SSL cipher is not displayed, indicating that SSL is not being used to secure our connection. See details below:

Current database:

SSL: Not in use Connection: Localhost via UNIX socket

What am I doing wrong?
