recovery file for my instance Tya-WP

Question

I hope you're well. I'm reaching out because of an urgent issue with my website. During a WordPress update, the auto-update feature failed and I attempted a manual update. Unfortunately, this process caused an error in the 'wp-config.php' file, rendering the website non-operational.

Your expertise in resolving this matter would be greatly appreciated due to the potential business impact. Please let me know when you're available to discuss further, and if you need any specific details or access credentials to look into the issue.

This is the error I got:
**Warning: mysqli_real_connect(): (HY000/1045): Access denied for user 'username_here'@'localhost' (using password: YES) in /opt/bitnami/wordpress/wp-includes/class-wpdb.php on line 1775
Access denied for user 'username_here'@'localhost' (using password: YES)

Error establishing a database connection**

Thank you in advance for your prompt attention.

Answer

Hello.  
From the nature of the error, it appears that access to the database has failed.  
First, please make sure that the database password, host name, and user name listed in wp-config.php are correct.

If there is a snapshot of Lightsail before the failure, it would be one way to restore the instance from here.
