bad gateway 500 according to:
10.5.3 502 Bad Gateway
The server, while acting as a gateway or proxy, received an invalid response from the upstream server it accessed in attempting to fulfill the request.
I've seen this to happen when a server send a strange response back, such as a malformed HTTP response header or a different status.
Is this happening only on the support.mozialla.com page? Is it constantly reproducible there or on any other page?
Unfortunetly I have not been able to reliably re-create the issue. It has also happened with the URL http://en.wikipedia.org/wiki/Certificate_signing_request. But even refreshing over and over the sometimes "problem" urls I can't get the error to hit. If you have any other thoughts feel free to post them, I'll continue trying to get more log data after one of the error occurs.
I have the same problem with the page www.segurosdelestado.com
Have solution for this? same problem.
please note that "502" responses can have a couple of different meanings. In order to tell you exactly what happens, more details are required. At least the exact version you are using and - if possible - a packet capture.
If you notice that it takes some seconds until 502 error page shows up (approx. 5-10 seconds) and you are running on 7.1.0, this could be related to timeout settings for the proxy. If the issue shows up immediatly, please provide some more data.
