Fix AWS WP DB Error

Job ID: 40388410

Budget: $10 – $30 USD

My WordPress Multisite on AWS is suddenly showing “Error establishing a database connection.” I can log in and supply the database credentials, but beyond that I’m not sure if anything on the EC2 side was recently altered. The site is wired to a GitHub-based pipeline, so once the outage is resolved I need to keep that automated deployment flow intact.

Here’s what I need from you:
• Diagnose and restore the database connection so the network of sites loads normally.
• Verify wp-config, security groups, DNS and any RDS or EC2 parameters tied to the failure.
• Confirm the existing GitHub → AWS pipeline still pushes code successfully (or patch it if the fix requires changes).
• Document the root cause and the steps you took so I can reference them in future incidents.

You will have SSH access, AWS console access and the credentials for the database. If additional permissions are required, I can obtain them quickly. The work is production-critical, so clear communication and minimal downtime are essential.
