HTTP Error 418 = “I’m a teapot”
It’s a humorous HTTP status code from an April Fools’ joke protocol called HTCPCP (Hyper Text Coffee Pot Control Protocol).
Meaning
The server is refusing to brew coffee because it is “a teapot”.

- Blocking bots/scrapers
- Rate limiting
- Debug/testing responses
- Custom API restrictions
- WAF/CDN security rules
Example
