Matchmaking won't work since yesterday

Hi, I'm having a problem with my matchmacking since yesterday. It was perfectly working, but, suddenly, my two clients can't find each other when then try to join a room. One client make a JoinRandomRoom, the latter fails since he's the first, so he creates a room. The second one make a JoinRandomRoom, and can't find the existing room. What is weird is that I didn't modify the code before the issue appeared, so it doesn't seem to be linked to my script. However, I get back to an older version of my game with git, a version during which I'm 100% sure it was working, but nothing changes, it doesn't work.
Moreover, I re-tried a few minutes ago, and it worked two times, and since, it doesn't work anymore, without having modified anything.
Any idea where it comes from ?

  • Hi @GabRay,

    Thank you for choosing Photon!

    Make sure to go through our "Matchmaking Checklist" especially "Best Region Considerations".

    Same issue here since today (when launching both clients on the same PC). I just updated PUN to 2.9.
    I'll try using ConnectToRegion()...

    Edit: setting the "Fixed region" field to "eu" in the PhotonServerSettings doesn't solve the issue, the second client is still getting an empty rooms list.
  • I'm having a similar issue. I just created a prototype of a networked shooter game using Photon and Unity, based on Photon's tutorial with Robot Kyle etc, I'm trying to join a random room, and if one doesn't exist I create one.

    My problem is that if I run two clients simultaneously on my PC both get the same server IP and can play against each other. But I cannot play against my friend who lives in another city here in Finland, he doesn't join my room and I don't join his.

    Once he got a server IP of 92.38.153.69 when I got 92.38.154.12. We both live in Finland (inside EU, the EU server gets the lowest ping).

    How could I debug this more? I'm just displaying server IPs and room names...
  • My problem is partially solved: My friend was sent to a Russian server (with a ping of 142ms) while I went to an EU server (54ms). I have no idea how that Russian server is the fastest for him as he lives around 60kms from my place. I'll add an option for server selection...

    For debugging, you can set a test region in the PhotonServerSettings, so BestRegion is no longer a factor.
    Alternatively, you can define a region whitelist per App in the Dashboad. This can be adjusted server-side and PUN 2 should make good use of it (and even re-ping all regions, if the list changed since last time you pinged all regions).

    Hope that helps.

    @vHelin: It would be interesting for us to get the traceroute info for the two servers app-eu.exitgames.com and app-ru.exitgames.com from you and your friend. On Windows, that's TRACERT.

    Hi, I still have this problem. I tried to connect to a fixed region on both clients, but they still can't find each others. I'm on PUN 2.6 (I re-imported it from 2.9 but somehow it is still on 2.6).
    I did follow the matchmaking checklist, and everything seems ok. My clients have same AppID, version, different userIDs, I don't use filters nor custom lobby.
