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 they actually work.

Troubleshooting Application Request RoutingTroubleshooting 502 Errors in ARR Troubleshooting 502 http://www.iis.net/learn/extensions/troubleshooting-application-request-routing/troubleshooting-502-errors-in-arr Errors in ARR By Richard MarrApril 9, 2012Tools Used in this Troubleshooter: IIS Failed Request Tracing Network Monitor Winhttp Tracing This material is provided for informational purposes only. Microsoft makes no warranties, express or implied. HTTP 502 - Overview When working with IIS Application Request Routing (ARR) deployments, one of the errors that you may see is "HTTP 502 - Bad Gateway". The 502.3 error means that - while acting as a bad gateway proxy - ARR was unable to complete the request to the upstream server and send a response back to the client. This can happen for multiple reasons - for example: failure to connect to the server, no response from the server, or the server took too long to respond (time out). If you are able to reproduce the error by browsing the web farm from the controller, and detailed errors are enabled bad gateway error on the server, you may see an error similar to the following: Figure 1 (Click image to expand) The root cause of the error will determine the actions you should take to resolve the issue. 502.3 Timeout Errors The error code in the screenshot above is significant because it contains the return code from WinHTTP, which is what ARR uses to proxy the request and identifies the reason for the failure. You can decode the error code with a tool like err.exe. In this example, the error code maps to ERROR_WINHTTP_TIMEOUT. You can also find this information in the IIS logs for the associated website on the ARR controller. The following is an excerpt from the IIS log entry for the 502.3 error, with most of the fields trimmed for readability: sc-status sc-substatus sc-win32-status time-taken 502 3 12002 29889 The win32 status 12002 maps to the same ERROR_WINHTTP_TIMEOUT error reported in the error page. What exactly timed-out? We investigate this a bit further by enabling Failed Request Tracing on the IIS server. The first thing we can see in the failed request trace log is where the request was sent to in the ARR_SERVER_ROUTED event. The second item I have highlighted is what you can use to track the request on the target se
