❗ WordPress "Error establishing a database connection" on new install via CyberPanel

Hi CyberPanel team,

I’m experiencing an issue while trying to install WordPress through CyberPanel. I receive the following error:

“Error establishing a database connection. This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at localhost:3306 could not be established.”

Steps already tried:

  • Verified MySQL service is running

This is a fresh install. Please advise on what might be misconfigured in CyberPanel or what logs to provide for deeper debugging.

Thanks in advance!
