Frequently Asked Questions
What is an HTTP status code?
HTTP status codes are three-digit numbers returned by web servers to indicate the result of a client's request: 2xx for success, 3xx for redirects, 4xx for client errors, 5xx for server errors.
What's the difference between 401 and 403?
401 Unauthorized means the request lacks valid authentication credentials. 403 Forbidden means the server understood the request but refuses to authorize it, even with valid credentials.
What does 502 Bad Gateway mean?
A 502 error means a server acting as a gateway or proxy received an invalid response from an upstream server. It usually indicates a temporary issue with the backend service.
