This is so frustrating, working on this auth system for like 6 days still not working same error all the time.

I changed my app type to "Consumer" in Facebook, and still does not work. Why there is no sample project for Auth for unity gaming service?

Signing in also not working.

Code (CSharp):

1. await AuthenticationService.Instance.SignInWithFacebookAsync(accessToken);

It throws same error unable to validate token. How does UGS validate token for facebook.

 

Currently I am using unity 2021.3.5f1 and Facebook SDK 11 (coz other are not working for me). All things are working fine like facebook auth, it signed in and gives access token. After supplying access token to SigninWithFacebookAsync it throws error ([Authentication]: Request failed: 401, {"title":"PERMISSION_DENIED","detail":"unable to validate token","details":[],"status":401}).

 

I completely started from scratch now it's working it's very very weird. New Facebook account and added New App as "Consumer Type" (this one is very important).

@Julian-Unity3D Thanks for replying cheers.

 

I have an error with facebook authentication that permissions denied 401
