FAQ: What are the Common HTTP Error Codes and Their Meanings?
HTTP error codes appear when there’s an issue with web page access or server response, each code signaling a unique type of issue. Below are some frequently encountered HTTP error codes and their meanings, following a structure to assist with easy troubleshooting.
HTTP 400 – Bad Request
Meaning: This error means the server couldn’t understand the request due to malformed syntax. It often happens if the request is incorrectly formatted or the URL structure is not valid.
Solution: Double-check the URL and ensure it follows the correct structure.
HTTP 401 – Unauthorized
Meaning: A 401 Unauthorized error indicates that the request requires authentication credentials that are missing or incorrect.
Solution: Ensure you have logged in or entered valid credentials.
HTTP 403 – Forbidden
Meaning: The server understands the request but refuses to authorize it. This can happen if users lack the permissions to access the requested resource.
Solution: Check your access permissions or consult the website administrator if you believe you should have access.
HTTP 404 – Not Found
Meaning: A 404 error indicates that the server cannot find the requested resource. It often occurs if a page has been removed, moved, or if there is a typo in the URL.
Solution: Confirm the URL and try again. If the issue persists, the page might no longer exist.
HTTP 500 – Internal Server Error
Meaning: A 500 error is a generic message indicating an unexpected condition on the server, which may prevent it from fulfilling the request. This can happen due to misconfiguration or issues with server-side code.
Solution: Wait and try again later. If you’re the server administrator, check server logs for more details on the issue or contact support@ipserverone.com
HTTP 502 – Bad Gateway
Meaning: This error occurs when a server, acting as a gateway or proxy, receives an invalid response from an upstream server. It can be due to connectivity issues between servers or configuration problems.
Solution: Refresh the page or try again later. Server administrators may want to verify upstream server configurations and connectivity.
HTTP 503 – Service Unavailable
Meaning: A 503 error means the server is temporarily unable to handle the request, often due to server maintenance or overload.
Solution: Retry after some time. For ongoing issues, check with the service provider or system administrator.
HTTP 504 – Gateway Timeout
Meaning: A 504 Gateway Timeout error occurs when a server acting as a gateway or proxy doesn’t receive a timely response from an upstream server, usually indicating a delay in server communication.
Solution: Refresh the page or try again later. Administrators may need to investigate upstream server response times.
HTTP 505 – HTTP Version Not Supported
Meaning: This error appears when the server doesn’t support the HTTP protocol version used in the request, which can happen if the client or server configuration is outdated.
Solution: Check if the client and server are compatible with the latest HTTP versions. Server administrators may need to update configurations.
