The plain HTTP request was sent to the HTTPS port. This is because in a secure connection, all data transmitted between a client and a server must be encrypted.
However, if a user accesses a website using a non-secure protocol like HTTP, their data will not be encrypted. This makes it vulnerable to various types of attacks such as phishing and data breaches.
Nginx is an open-source web server software that can be used to create secure connections between a client and a server. When you enable HTTPS on your Nginx installation, it will encrypt all data transmitted over the connection. This means that even if an attacker intercepts the request, they will not be able to read or modify the sensitive information.
An HTTP request is a fundamental aspect of any web application. It involves sending requests from clients (like browsers) to servers, which respond with data. However, if an attacker can intercept these requests, they may be able to manipulate or exploit them for their own gain.
In recent years, there have been several high-profile attacks that exploited vulnerabilities in HTTP requests. For example, the WannaCry ransomware attack in 2017 was largely attributed to a vulnerability in Windows operating systems that allowed attackers to execute malicious code on infected devices.
