What could NOT be the cause of a WordPress site not responding after setup?

Forgotten to open port 80/443 on the security group.
Elastic Load Balancer health check is failing.
No ALIAS configuration for the A record.
Locked port 22 to a specific IP address.

The correct answer is: Locked port 22 to a specific IP address.

The reason why "Locked port 22 to a specific IP address" could not be the cause of a WordPress site not responding after setup lies in the function of port 22. Port 22 is primarily used for SSH (Secure Shell) access to a server, which allows administrative access and management of the server itself. This port does not directly impact how a web application, such as a WordPress site, serves content over HTTP (port 80) or HTTPS (port 443). If the site is not responding, the issue would typically be related to web traffic management, such as the opening of ports for web services, health checks on load balancers, or DNS configurations affecting how visitors reach the site. The state of port 22 does not affect these aspects, and therefore, locking it down would not result in the WordPress site being unresponsive to end-users. In contrast, failing health checks on an Elastic Load Balancer, forgotten configurations for required ports in the security group, or issues with DNS records that direct traffic to the site could indeed cause the site not to respond as they directly relate to the delivery and accessibility of the web application itself.
