"Profile Required" error after sign-in

When I press enter at the initial screen, it asks me to sign into a profile. When I do so and click “Let’s play” an error is shown: “Profile Required: Please sign in to your profiel”. I just did that. What’s up? Anyone know how to fix this?
I have an xbox live silver account.

I fixed the problem: You need to sign into the Xbox app first before signing into the Halo app or Halo 5 Forge
