How I can access the run time application log to fix 404 Error

Hello, My application is deployed and I login correctly, but I got the 404 Error when I used its functions and when I tried to check the run time log to resolve the problem I got the message " There are no runtime logs in this time range " . Please direct me to how I can check the application log?
