Why I got an error request every 5 minutes in an Azure App Service

azure, azure-application-insights, azure-web-app-service

Solution

There is a setting named 'Always on' in App Service's configuration, and it's works fine when I turned off this setting.

Problem

I have a java web app on Azure, and I got failed requests in it's Application Insights. It look likes someone are calling 'http://myApp.azurewebsites.net/error' every 5 minutes, but I do not have this interface, so there are many failed requests with 404 in Application Insights. Then I add this interface in app, but there are still many failed requests with 404 code. I have no idea about those requests, I do not know where are them from or what do them want to do. Did I set wrong configurations in my app?
