- 1. Refresh the page: Many 5xx errors are temporary and clear on a retry.
- 2. Wait a few minutes and try again: Especially for 503s during traffic spikes or maintenance.
- 3. Clear your cache or try incognito mode: Rules out a stale cached version.
- 4. Try a different browser or device: Confirms it's the site, not you.
- 5. Contact the website owner: If it persists, let them know that there is a problem on their end.
A server error is a problem that happens on a website's server, not on your computer or phone, that stops the server from completing your request. You'll usually see it as a 5xx HTTP status code (like 500 or 503), and in almost every case it is not your fault.
This guide explains what a server error means, the different types you might run into, why they happen, how to fix them (whether you're a visitor or a site owner), and how to prevent them.
What is a Server Error?
A server error is a technical issue that occurs when a server fails to respond properly to clients (users or other systems). These errors can arise from various causes such as misconfigurations, overload, hardware failures, or software issues. Server errors are identified by HTTP status codes and are commonly known as 500-series errors. These errors indicate that the server is experiencing an internal issue and cannot provide a proper response to the request.
This is what separates it from a client error (the 4xx range, like 404 Not Found), which points to a problem with the request itself.
In short: 5xx = the server's problem. 4xx = the request's problem.
What does a server error mean for you?
For most people, a server error simply means the website you're trying to reach is temporarily broken or overloaded. There's usually nothing wrong with your device, browser, or internet connection.
| Server errors (5xx) | Client errors (4xx) | |
|---|---|---|
| Where the problem is | On the website's server | With the request / your access |
| Whose fault | The website's | Often the request (wrong URL, no permission) |
| Common examples | 500, 502, 503, 504 | 404 (Not Found), 403 (Forbidden) |
| Can you fix it yourself? | Rarely - usually wait or retry | Sometimes - check the URL, log in |
Common Server Errors and Their Causes
Most server errors fall into a handful of common 5xx codes. Here's what each one means in plain language:
500 Internal Server Error
This general error occurs when the server fails to process a request. Possible causes include:
Example: If an e-commerce site shows a "500 Internal Server Error" during the payment process, a script running on the server might be throwing an error.
502 Bad Gateway
This error occurs when the server does not receive the expected response from another server. Common causes include:
Example: If a news site receives "502 Bad Gateway" errors while delivering content via a CDN, there may be an interruption between the server and the CDN provider.
503 Service Unavailable
This error arises when the server cannot respond to requests due to being temporarily overloaded or undergoing maintenance.
Example: If your e-commerce site gives a "503 Service Unavailable" error during a large discount campaign, the server may not be able to respond due to excessive traffic.
504 Gateway Timeout
Occurs when the server does not receive a timely response from another server to which it is connected.
Example: If a reservation system receives a "504 Gateway Timeout" error while fetching hotel information, it may indicate that the main server is taking too long to respond.
505 HTTP Version Not Supported
This error occurs when the version of the HTTP request made by the client is not supported by the server.
Example: If a user tries to connect to a website from an outdated browser and receives a "505 HTTP Version Not Supported" error, the browser may need to be updated.
How to fix a server error
What you can do depends on whether you're visiting the site or you own it.
If you're a visitor
You can't fix the server, but these steps rule out anything on your side and sometimes get you through:
If you own the website
It is important to take the following measures to minimize server errors:
Maintain Adequate Server Resources
Ensure that your server has sufficient resources such as CPU, RAM, and disk space. Transitioning to a scalable infrastructure can be beneficial in case of increased traffic.

Conduct Regular Maintenance and Updates
Regularly update the software, operating system, and security patches on your server. Unupdated software can lead to security vulnerabilities and performance issues.
Example: Websites using CMS systems like WordPress can become vulnerable to security threats if not regularly updated.
Use Load Balancing and CDN
For websites experiencing high traffic, using load balancing and Content Delivery Network (CDN) can prevent the server from becoming overloaded, providing faster and more reliable services.
Example: A website catering to a global audience can use a CDN to respond faster to users in different regions.
Implement Logging and Monitoring Systems
Use advanced monitoring tools and error logs to track problems in real-time and to detect server errors early and intervene.
