5xx Server Error Status Codes

Showing 11 status codes

HTTP 5xx status codes indicate server-side errors where the server failed to fulfill a valid request. Unlike 4xx errors, these are not the client's fault—something went wrong on the server that prevented it from completing the request.

The most common 5xx codes are 500 Internal Server Error (generic server failure), 502 Bad Gateway (invalid response from upstream server), 503 Service Unavailable (server temporarily overloaded or under maintenance), and 504 Gateway Timeout (upstream server didn't respond in time).

When users encounter 5xx errors, they should typically retry later or contact the site administrator. For developers, these errors require server-side investigation through logs, monitoring, and debugging to identify and fix the underlying issues.

5xx Server Error Status Codes FAQ

What causes a 500 Internal Server Error?

500 Internal Server Error is a generic catch-all error indicating something went wrong on the server. Common causes include unhandled exceptions in code, database connection failures, misconfigured server settings, or exhausted server resources.

What is the difference between 502 and 504 errors?

502 Bad Gateway means the server acting as a gateway received an invalid response from an upstream server. 504 Gateway Timeout means the gateway didn't receive any response from the upstream server within the time limit. Both indicate issues with backend services.

What does 503 Service Unavailable mean?

503 Service Unavailable indicates the server is temporarily unable to handle the request, usually due to maintenance or being overloaded. It often includes a Retry-After header suggesting when to try again. This is typically a temporary condition.
