The plain HTTP request was sent to HTTPS portnginx1240

When a plain HTTP request is sent to an HTTPS port, it means that the client is attempting to establish an insecure connection over a secure port.

In this case, the server is running Nginx version 1.24.0 and it has received a request that is not using the secure HTTPS protocol on the port designated for HTTPS communications.

Nginx is a popular web server and reverse proxy server that can be configured to handle both HTTP and HTTPS traffic. By default, Nginx listens on port 80 for HTTP requests and port 443 for HTTPS requests. If a plain HTTP request is sent to the HTTPS port (443), Nginx will typically respond with an error message or redirect the client to the correct HTTPS URL
