I have rebooted https://www.theguardian.com/technology/askjack/2013/aug/01/502-bad-gateway-error my PC and used 'system restore' several times, but haven't been able to clear it. Do you know how to sort this out? Viv The 'Bad Gateway' error is coming from the server, and usually has nothing to do with your PC. It may just be that the site is overloaded. Often, simply refreshing or reloading the page (Ctrl-F5) will work, but sometimes the problem can persist for days. If so, you could log the time(s) and browser version and submit an error report to the webmaster, because 502 errors can be caused by bugs in the associated PHP programming. In this case, email the admin team at myfreecycleadmin@freecycle.org. If it's an intermittent fault, the simplest option is to wait for 10 minutes and then try again. There are a few things that you can do to try to get through to a site when you get a 502 Bad Gateway error. It's hard to know whether they actually work. It might be that doing them is simply introducing a delay and the site would have worked if you hadn't bothered.

It includes codes from IETF internet standards, other IETF http://www.tech-faq.com/502-proxy-error.html RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must error 502 recognise these five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional 504 gateway timeout decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

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against external or internally-based Internet threats, and 2- The client or server computers are misconfigured or using outdated software.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’s response (502 Proxy Error). How to Fix 502 Proxy Errors (Client Side) One of the most frustrating things for the average computer user is determining where the problem resides when receiving the 502 Proxy Error. Before engaging the webmaster of the site or one’s Internet Service Provider (ISP), it is prudent to troubleshoot the client computer to make sure that it is not the reason that the error is being thrown. Step 1 – Close the Internet browser that you
