Hello! Sometimes our users are getting Google-styled 502 Bad Gateway error page instead of our server response on POST request. According to Stackdriver Logging, we are not to blame at this, there are no errors, the request is just like another successful requests. Here is example request id if necessary: 5975d28e00ff07b8225bcaf1340001737e626c69747a74696e7961726d7970616e6f72616d696300017374616765000100.
We are using frontend instances of App Engine Standard Environment with Python 2.7 and Werkzeug wsgi server and don't return 502 status code anywhere. Please help us with identifying the error source. Thank you! -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
