Common Webpage Error Codes and Their Meanings
Webpage error codes are categorized into client-side errors (4xx) and server-side errors (5xx). Each code provides specific information about the issue, helping users diagnose and fix problems efficiently.

Client-Side Errors (4xx)
These errors occur due to issues on the user’s end, such as incorrect URLs or unauthorized access attempts.
- 400 Bad Request: The server cannot process the request due to malformed syntax.
- 401 Unauthorized: Authentication is required to access the resource.
- 403 Forbidden: The server refuses to fulfill the request, often due to permission issues.
- 404 Not Found: The requested resource is unavailable or does not exist.
Server-Side Errors (5xx)
These errors indicate problems on the server hosting the webpage.
- 500 Internal Server Error: A generic server error with no specific cause provided.
- 502 Bad Gateway: The server acting as a gateway received an invalid response.
- 503 Service Unavailable: The server is temporarily unable to handle requests.
- 504 Gateway Timeout: The server did not receive a timely response from another server.
Troubleshooting Steps for Common Errors
Resolving webpage errors often involves checking both client and server-side configurations. Below are step-by-step solutions for frequent issues.
Fixing 404 Not Found Errors
This error occurs when a webpage is moved or deleted. To resolve it:
- Check the URL for typos.
