Please Explain This 502 Bad Gateway Error
WhatsApp Share on Messenger I keep getting an error message, 502 Bad Gateway nginx/0.7.67, when I try to access the Freecycle site. I have rebooted 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

includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The 502 bad gateway nginx/1.4.6 (ubuntu) first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases used are the standard wordings, https://www.theguardian.com/technology/askjack/2013/aug/01/502-bad-gateway-error 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 decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in https://en.wikipedia.org/wiki/List_of_HTTP_status_codes the response payload and in documentation; not in the place of an actual HTTP status code).

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line.

Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request's headers, a client must send Expect

HTTP status codes are three-digit codes, and are grouped into five different classes. The class of a status code can be quickly identified 502 bad by its first digit: 1xx: Informational 2xx: Success 3xx: Redirection 4xx: Client Error 5xx: Server Error This guide focuses on identifying and troubleshooting the most commonly encountered HTTP error codes, i.e. 4xx and 5xx status codes, from a system administrator's perspective. There are many situations that could cause a web server to respond to a request with a particular error code--we will cover common potential causes and solutions. Client and Server Error Overview Client errors, or HTTP status codes from 502 bad gateway 400 to 499, are the result of HTTP requests sent by a user client (i.e. a web browser or other HTTP client). Even though these types of errors are client-related, it is often useful to know which error code a user is encountering to determine if the potential issue can be fixed by server configuration. Server errors, or HTTP status codes from 500 to 599, are returned by a web server when it is aware that an error has occurred or is otherwise not able to process the request. General Troubleshooting Tips When using a web browser to test a web server, refresh the browser after making server changes Check server logs for more details about how the server is handling the requests. For example, web servers such as Apache or Nginx produce two files called access.log and error.log that can be scanned for relevant information Keep in mind that HTTP status code definitions are part of a standard that is implemented by the application that is serving requests. This means that the actual status code that is returned depends on how the server software handles a particular error--this guide should generally point you in the right direction Now that you have a high-level understanding of HTTP status codes, we will look at the commonly encountered errors. 400 Bad Request The 400 status code, or Bad Request error, means the HTTP request that was sent to the server
