Updated: July 20, 2016 Comments: 1 What does 502 Bad Gateway mean? A 502 Bad Gateway indicates that the edge server (server acting as a proxy) was not able to get a valid or any response from the origin server (also called upstream server). KeyCDN returns a 500 Origin Not Reachable if a 502 Bad Gateway occurred. What does 502 Bad Gateway mean? What are the reasons for 502 Bad Gateway responses? Domain name not resolvable: The domain name is not resolving to the correct IP or it does not resolve to any IP. It is important to note that DNS changes could take same time until they are global fully propagated and active. This is very dependant on the DNS TTL defined per record. Origin server down: The server is not reachable, either because it is down or there is no connectivity to the server given. Firewall blocks request: A firewall blocks the communication between the edge servers and the origin server. This can also be c
This server received an invalid response from an upstream server it accessed to fulfil the request. This usually does not mean that the upstream http://www.checkupdown.com/status/E502.html server is down (no response to the gateway/proxy), but rather that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data. Given that Internet protocols are quite clear, http://www.tech-faq.com/502-proxy-error.html it often means that one or both machines have been incorrectly or incompletely programmed. Fixing 502 errors - general This problem is due to poor IP communication between back-end computers, possibly including the server error Web server at the site you are trying to visit. Before analysing this problem, you should clear your browser cache completely. If you are surfing the Web and see this problem for all Web sites you try to visit, then either 1) your ISP has a major equipment failure/overload or 2) there is something wrong with your internal Internet connection e.g. your firewall is not functioning 502 server error correctly. In the first case, only your ISP can help you. In the second case, you need to fix whatever it is that is preventing you reaching the Internet. If you get this problem for only some of the Web sites you try to visit then it is likely to be a problem at those sites i.e. one of their pieces of equipment is failing/overloaded. Contact the people at those sites. Fixing 502 errors - CheckUpDown Our service monitors your site for HTTP errors like 502. Use of proxies and caching is increasing on the Web. Our CheckUpDown robot will always try to "drill through" to the real computer that actually hosts the Web site, but we do not have complete control over where our HTTP request actually ends up. If only one link in the chain of computers dealing with our HTTP request is broken, then an error such as 502 can easily occur. Please contact us (email preferred) whenever you encounter 502 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of the Web server software so that they can
a proxy server. The problem is typically caused for one of two reasons: 1 – The Internet Security and Acceleration (ISA) is configured to throw a proxy error to help guard against external or internally-based Internet threats, and 2- The client or server computers are misconfigured or using outdated software. What is a 502 Proxy Error? A 502 proxy error is typically thrown in the HTTP cycle. When the error occurs, a server (does not have to be a Web server) is filling a role similar to a proxy or a gateway server. When a client computer sends an HTTP request (typically a web browser, but can be any software application that is capable of making an HTTP request), it will pass through the server in order to obtain access to the desired URL. The proxy or gateway subsequently receives a 502 error, or invalid response, from the server located “upstream” in the attempt to fulfill the client request. The majority of the time the error is thrown, the upstream server is functioning appropriately. The proxy or gateway and upstream servers just cannot agree on the appropriate protocol for exchanging the information requested in the original client HTTP request. In many of these cases, either the proxy or upstream server are not configured correctly or are running incompatible software. Why Does a 502 Proxy Error Get Thrown? During a typical web browsing session, the following is an example of the classic HTTP cycle when a client computer and web server are communicating: Client Computer: The IP address of the desired website will be obtained from the URL of the site from the DNS server. Client Computer: The computer obtains an IP socket connection to the desired IP address and then sends an HTTP data stream through the IP address. Web Server: HTTP data is sent back to the client computer in response to the original HTTP request. The HTTP response will include status codes and other useful information for the client computer. Client Computer: If there is an error in the client’s request or server’s ability to respond, there will be an HTTP error code of 502 included in the server
