Introduction to 5xx Server Errors – 5xx server errors are HTTP status codes. They indicate a problem with the website’s server. Unlike client-side errors (4xx), these errors mean the server failed to complete a request.
When a 5xx error occurs, users see messages like “Internal Server Error.” These errors harm user experience and SEO. Fixing them quickly is important.
Common Types of 5xx Server Errors
Here are the most frequent 5xx status codes:
1. 500 Internal Server Error
- A generic error when the server fails.
- No specific cause is mentioned.
- Often due to misconfigured server settings.
2. 501 Not Implemented
- The server does not support the requested feature.
- Common when using outdated server software.
3. 502 Bad Gateway
- One server acts as a gateway and gets an invalid response.
- Common in proxy servers or CDN issues.
4. 503 Service Unavailable
- The server is temporarily down for maintenance or overload.
- Fix by checking server load or restarting services.
5. 504 Gateway Timeout
- A server acting as a gateway did not get a timely response.
- Often caused by slow server communication.
