Hi Ivan, This error occurs when all the request handlers for your app are busy processing requests, and incoming requests are queued for more than 10 seconds. This is usually because your app takes a very long time to process requests, or because you're doing 'long polling' or something else that causes your app to artificially inflate the amount of time it takes to return a response.
