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