400 The Plain Http Request Was Sent To Https Port
This article discusses the security vulnerability in web development and how it relates to cloudflare-related issues. It explains what 400 errors, HTTP requests, and more are.
What is a 400 error?
A 400 error, also known as an "Invalid Request" or "Bad Gateway" error, is a type of HTTP status code that indicates the server encountered an unexpected request. It's often used to describe situations where the client (user) has made a wrong assumption about the server's behavior.
How do 400 errors relate to cloudflare-related issues?
Cloudflare is a popular web application security service that helps protect websites from various threats. However, in some cases, it can also introduce vulnerabilities that lead to 400 errors. One common issue is when Cloudflare's automated scan process mistakenly identifies certain requests as malicious and blocks them, causing the server to return an invalid response.
