Warning: mysqli_real_connect(): (HY000/3159): Connections using insecure transport are prohibited while --require_secure_transport=ON

I followed this tutorial here “https://www.digitalocean.com/community/tutorials/how-to-set-up-a-remote-database-to-optimize-site-performance-with-mysql-on-ubuntu-16-04” to Set Up a Remote Database with MySQL on Ubuntu 16.04.

I have also download wordpress onto the web server. However when i attempt to run the wordpress install from browser, I get this error (wordpress debug mode set to true):- Warning: mysqli_real_connect(): (HY000/3159): Connections using insecure transport are prohibited while --require_secure_transport=ON. in /var/www/html/wp-includes/wp-db.php on line 1538

What is causing this error and How do I fix this error?

I do not believe the answer above is sufficient, if you want to establish an encrypted connection between your database server and web server.

I dealt with the same problem and solved it by changing the ownership of the generated ca.pem, server-cert.pem and server-key.pem files from root to mysql.

go to sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

just remove the “require_secure_transport = on” than sudo systemctl restart mysql

now you can check login from webserver to database server
