HTTP 424 Failed Dependency

HTTP 424 Failed Dependency means the request failed because another action it depended on failed (WebDAV). The request contains an error or can’t be fulfilled. Retrying unchanged won’t help.

Class
4xx Client error
Standard
RFC 4918
Cacheable by default
No
Safe to retry
No
Go constant
http.StatusFailedDependency

What HTTP 424 means

In WebDAV batch operations, if one step fails, later steps that depend on it fail with 424. Some APIs reuse it when an upstream dependency rejected part of a request.

Retrying

No. Fix the request first; sending it again unchanged will get the same response.

Example response

HTTP/1.1 424 Failed Dependency
Date: Wed, 21 Oct 2026 10:30:00 GMT
Content-Type: application/json

How to return 424

Node.js (Express)
res.status(424).json({ error: 'Failed Dependency' });
Python (FastAPI)
from fastapi import HTTPException

raise HTTPException(status_code=424, detail="Failed Dependency")
Go (net/http)
http.Error(w, http.StatusText(http.StatusFailedDependency), http.StatusFailedDependency)
nginx
location /private/ {
    return 424;
}
