My Code

Code (CSharp):

1.  
2.              // From within a NetworkManager Behaviour
3.             StartMatchMaker();
4.             matchMaker.ListMatches(0, PageSize, "", response =>
5.             {

- I do have my app Id in player settings
- It was working 5 minutes ago
- I have tried 2 different cloud id's

Edit, The cloud website presents this error with my project (Unable to load project. (400))

 

same problem, did you find a solution?

 

No, I reported the issue and have yet to hear anything from UT.

 

Thanks for reaching out JeremyUnity

5.1.1f1

Both website and editor say I am up to date.

 

The latest release right now is 5.1.1p4, found here: http://unity3d.com/unity/qa/patch-releases/5.1.1p4

Hmmm... I am having a very similar problem:

Running 5.5.0f3 Personal

Code (CSharp):

1.    
2. NetworkMatch matchMaker;
3. List<MatchInfoSnapshot> matches;
4.  
5.     public override void Update()
6.     {
7.         if ( Time.time >= nextUpdate )
8.         {
9.             nextUpdate = Time.time + 1.0f;
10.  
11.             if ( matchMaker == null )
12.                 matchMaker = new NetworkMatch();
13.  
14.             matchMaker.ListMatches( 0, 10, "", false, 0, 0, OnMatchList );
15. ...
16.         }
17.     }
18.  
19.     public void OnMatchList( bool success, string extendedInfo, List<MatchInfoSnapshot> newMatches )
20.     {
21.         if ( success && newMatches != null )
22.         {
23.             matches = new List<MatchInfoSnapshot>();
24.             foreach ( MatchInfoSnapshot match in newMatches )
25.                 matches.Add( match );
26.         }
27.     }
28.  

Causes the error:

Code (CSharp):

1.  
2. NullReferenceException
3. UnityEngine.MonoBehaviour.StartCoroutine (IEnumerator routine) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/MonoBehaviourBindings.gen.cs:54)
4. UnityEngine.Networking.Match.NetworkMatch.ListMatches (UnityEngine.Networking.Match.ListMatchRequest req, UnityEngine.Networking.Match.DataResponseDelegate`1 callback) (at C:/buildslave/unity/build/Runtime/Networking/Managed/MatchMakingClient.cs:334)
5. UnityEngine.Networking.Match.NetworkMatch.ListMatches (Int32 startPageNumber, Int32 resultPageSize, System.String matchNameFilter, Boolean filterOutPrivateMatchesFromResults, Int32 eloScoreTarget, Int32 requestDomain, UnityEngine.Networking.Match.DataResponseDelegate`1 callback) (at C:/buildslave/unity/build/Runtime/Networking/Managed/MatchMakingClient.cs:302)

Make sure NetworkMatch is created using "AddComponent" instead of "new"
