The response time limit <https://cloud.google.com/appengine/docs/flexible/python/how-requests-are-handled#response_limits> in App Engine is one hour, so it is intended that you receive the error message after one hour. Using manual scaling in the Flexible environment doesn’t affect that.
Could you tell us why you need your requests to last for over an hour? It might be that App Engine is not the best suited product for your needs. You should also note that very heavy traffic might result in your server serving a 504 error. I recommend that you scale up the number of your instances <https://cloud.google.com/appengine/docs/flexible/python/configuring-your-app-with-app-yaml#services> based on your traffic estimation or set it as automatic scaling. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
