[Unity 5]matchmaking : matches not visible - unity3d

Question

I need your help please because I have an issue about matchmaking. I try to make a Pong playable online. When i use NetworkHUD, and I use Matchmaker, I can create a match, and the other app (on the same computer for now) detach it and can join it. But, when I don't use it, but I use matchmaker manually, I can create a match, I have a success response, I can find this match in the same app, but, in my second app, I can't find match created by the first app.
Can you help me?
Here are two functions in which I create match :
public void matchmaking()
{
nm.StartMatchMaker();
networkMatch.ListMatches(0, 20, "", OnMatchList);
Debug.LogError ("NBR MATCH " +matchList.Count);
if (matchList.Count == 0)
{
CreateMatchRequest match = new CreateMatchRequest();
match.name = "OrionPongRoom";
match.size = 2;
match.advertise = true;
match.password = "";
networkMatch.CreateMatch(match, OnMatchCreate);
}
else
Debug.Log ("******matches found"+matchList.Count);
}
void OnMatchCreate(CreateMatchResponse matchResponse)
{
if (matchResponse.success)
{
Debug.LogError("Create match succeeded");
matchCreated = true;
MatchInfo matchInfo = new MatchInfo(matchResponse);
Utility.SetAccessTokenForNetwork(matchResponse.networkId, new NetworkAccessToken(matchResponse.accessTokenString));
nm.StartHost(matchInfo);
NetworkServer.Listen(9000);
//NetworkServer.Listen(new MatchInfo(matchResponse), 9000);
}
else
{
Debug.LogError ("Create match failed");
}
}

Answer 1

You need to write
if (matchList.Count == 0)
{
CreateMatchRequest match = new CreateMatchRequest();
match.name = "OrionPongRoom";
match.size = 2;
match.advertise = true;
match.password = "";
networkMatch.CreateMatch(match, OnMatchCreate);
}
else
Debug.Log ("******matches found"+matchList.Count);
in OnMatchList method.
void OnMatchList(ListMatchResponse matchList)
{
if (matchList.Count == 0)
{
CreateMatchRequest match = new CreateMatchRequest();
match.name = "OrionPongRoom";
match.size = 2;
match.advertise = true;
match.password = "";
networkMatch.CreateMatch(match, OnMatchCreate);
}
else
Debug.Log ("******matches found"+matchList.Count);
}
Because of Network Delays etc, matchmaking server can not send response synchronous.
