Error 502 Nginx On Server Centos
What is Error 502 Nginx On Server Centos?
Error 502 Nginx On Server Centos is a type of HTTP status code error that occurs when a server is unable to complete a request because of an unidentifiable issue. It is a type of server-side error that cannot be handled by the client, meaning the problem exists on the server side. The request is usually sent to the server via the client’s computer, and the server responds with a corresponding code to indicate the request’s status. This code can range from 200 to 5xx, with 502 being a 5xx status code.
The 502 error specifically occurs when the server cannot complete the request due to conflicting server configurations, a misconfigured firewall, or an overloaded server, meaning it can’t handle any more requests. This error is usually seen when the client is attempting to access a website, as the server may not have enough resources to process the request.
What Causes Error 502 Nginx On Server Centos?
Error 502 Nginx On Server Centos is caused by a number of things, but most commonly it is a result of a misconfigured firewall, over-utilized server, or Nginx server configuration issue. When a server is overburdened and unable to handle the number of requests coming in, the server may return a 502 error. Additionally, if the server’s firewall is configured incorrectly or the Nginx server configuration is incorrect, the web server will be unable to process the request and return a 502 error.
A 502 error is also caused by an incorrect proxy configuration. Proxy server settings can often be set-up incorrectly, meaning the proxy server is unable to pass requests through to the web server correctly. In this situation, the proxy server will return a 502 error to the client computer.
How to Fix Error 502 Nginx On Server Centos
The first step to fixing the Error 502 Nginx On Server Centos is to identify the root cause of the error. If the server is being overloaded with requests, the first thing to do is to reduce the load on the server by limiting the number of incoming requests or by using a server load balancer.

It is important to review the server configuration and make sure the firewall is set up correctly so that the requests can be processed correctly. Additionally, if the Nginx server configuration has any errors, these should be corrected.
In the case of an incorrect proxy configuration, it is important to make sure that the correct settings are being utilized. All proxy server settings should be checked to make sure they are configured correctly. Once these settings are correct, the 502 error should be resolved.
