Error Code 502 Proxy Error
HTTP provides an orderly way for your Web browser to communicate with Web servers -- the machine chatter that goes on behind the scenes of your Internet experience. As a part of HTTP, whenever your browser interacts with a https://support.microsoft.com/en-us/kb/2423401 server, such as when you attempt to load a Web page, the server responds with an Internet status code telling the browser how the interaction went. The most common one is code 200, a generic message meaning that everything went fine. These codes are always present, but your browser doesn't typically show them to you, unless something goes wrong. Code 404 is the best-known HTTP error code, indicating that the server couldn't find what your browser was https://www.techwalla.com/articles/how-to-fix-a-502-proxy-error looking for, but code 502 also shows up from time to time.Code 502: Bad GatewayHTTP error code 502 indicates a "bad gateway" or "bad proxy." When you visit a website, your browser doesn't necessarily communicate directly with the server that hosts the site. Often there are middleman Web servers along the way called "gateways" that route Web traffic between networks. If something goes wrong between the gateway server and another server upstream -- which could be either the destination server or another gateway server -- the status code that makes its way back to you is code 502. It's not a very informative message, telling you only that the gateway server received an invalid response. The actual problem could lie with the upstream server or with the gateway server itself.Main Sources of 502 ErrorsIf you get a 502 error only for a specific website, it usually suggests a problem with the website's server. On the other hand, if you get 502 errors for all websites, it probably means that your Internet service provider is having a technical problem in your neighborhood. Give them a call to report the outage; and if you use a proxy server for privacy or to bypass access restrictions, a 502 error could indicate that the proxy server has some bad or difficult programming -- which is not uncommon. In this case, you could try going wit

Some reasons why this might happen: Tomcat may have crashed The web application did not respond in time and the request from Apache timed out The Tomcat threads are timing out A network device is blocking the request, perhaps as some sort of connection timeout or DoS attack prevention system If the problem is related to timeout settings, you may be able to resolve it by investigating the following: ProxyTimeout directive of Apache's mod_proxy Connector config of Apache Tomcat Your network device's manual share|improve this answer answered Jan 29 '14 at 2:18 rmeakins 899611 add a comment| up vote 16 down vote Add this into your httpd.conf file Timeout 2400 ProxyTimeout 2400 ProxyBadHeader Ignore share|improve this answer edited Sep 6 at 16:52 Ian Hunter 3,46973559 answered Feb 18 '14 at 9:23 Albert Maclang 16112 8 Try it why?
