Resolved I can sign-in to UGS when running the build in my computer but not in another with AnonymouslyAsync

I've been testing out my game with two builds in my own machine and it works fine. But when I sent the build to a friend for testing, it won´t allow him to sign-in with the SignInAnonymously() function. The code managing the signing is

Code (CSharp):

1.    
2. private async void Start()
3.     {
4.  
5.         await UnityServices.InitializeAsync();
6.        
7.         if(!AuthenticationService.Instance.SessionTokenExists)
8.         {
9.             return;
10.         }
11.         try
12.         {
13.             await AuthenticationService.Instance.SignInAnonymouslyAsync();
14.         }
15.         catch(AuthenticationException ex)
16.         {
17.             Debug.Log(ex);
18.         }
19.  
20.     }

Its basically a copy from what the documentation recommends for signing players even if cached already, so i don´t really get why it wouldn´t work in another computer.

 

Unity Editor is 2021.3.18f1, and Unity Authentication is 2.4.0, full code of the Relay Network Manager below. For context, I have a button that just runs JoinRelay(text) and uses the text writen inside an InputField, when it's pressed the "player isn't signed in" exception ocurrs.

 

Forgot to answer, removing the if statement solved the problem! Thank you! The exception wasn´t the problem Im guessing, but the if statement was shutting down the rest of the code immediately
