Wordpress AWS Error establishing a database connection

Question

In one of my project, I am getting this error while accessing the website.

When I restarted RDS instance, the problem was solved and website was running.

After 2 days, again I am getting the same error. But after restarting RDS, Problem is solved. I am not able to figure out this problem. Please help.

did you try after define('WP_ALLOW_REPAIR', true); in wp-config file? — Vignesh Pichamani

Are you using the END POINT of the RDS instance or querying the IP address and then using it ? Please use END POINT which would be in the format abcdef.us-east-1.rds.amazonaws.com — Naveen Vijay

Look at this tutorial, it covers the whole process but you may skip to the last part: Using Amazon RDS with your WordPress installation

I had the same issue with AWS Lightsail.

Solved as follows :

test ! -f "/opt/bitnami/common/bin/openssl" && echo "Approach A" || echo "Approach B"

test -d /opt/bitnami/mariadb && echo "MariaDB" || echo "MySQL"

sudo systemctl restart apache2 or sudo service apache2 restart
