aNag not working

Hi, I am trying to connect icinga with aNag for Android, but when I try, it gives me a not found error message.
What could it be?

This looks like HTTP 404. Are you sure the API is accessible on plain text port 8080? By default this is port 5665 and needs https connection. Also the user has to be added to api-users.conf.

thanks. Its problem was number port. now it shows another problem “the target ser ver failed to respond” (attached screenshot) . I created user on ApiUsers.conf like you say (attached screenshot).

Its problem was the url. I used http when was https.
