There are many differences between the standard and flexible runtimes. Some of these differences require that changes be made to the underlying code and may otherwise generate errors. As mentioned in a previous post, if you believe this to be an issue with the platform, please file a new issue on the App Engine public issue tracker <https://code.google.com/p/googleappengine/issues/list>. Please be sure to include the following:
- Output of running tracert to your application. The 502/503 error suggests this might be an issue with the nginx proxy before your application instance. tracert may reveal this. - Handler entries in the app.yaml or appengine-web.xml - Dispatch rules in dispatch.yaml or dispatch.xml - Any log entries for HTTP requests to the URLs returning 502/503 - Code sample for the error-producing handlers so we may deploy and test this for ourselves With the above information, we should be in a better position to determine if this in fact a platform issue. If not, we may be able to determine the cause of said errors in user code as well.
