Failed to get server instance

Hello.

So... I understand that this problem has been here many times, but I could not find a solution for my case on the forum.

We use self-hosted on our own server. Now our average CCU has increased to 3000 users and we are facing an error:

ReturnCode: 32762 (Failed to get server instance.)

This happens when the player tries to create a new room. At the same time, it can easily connect to existing rooms.

This is definitely not related to the CPU load, since we have an average value of 25%. Perhaps this is somehow related to the load on the network channel, since it does not exceed 100 MB/s. But we have 1 Gb/s on our server.
Something restricts further use. But we don't know what the reason is.

Does anyone know what it could be?

Thanks.

  • Which sort of license do you use? Does it have a CCU cap?

    We use an unlimited license.
  • hi, @Shockapp

    sorry for late response.

    Please check logs for GameServer. you should see something like this:
    INFO Photon.Common.LoadBalancer.LoadShedding.FeedbackController - Transit CpuUsage from Lowest to Level1 with input 11
    INFO Photon.Common.LoadBalancer.LoadShedding.WorkloadController - FeedbackLevel changed: old=Lowest, new=Level1

    this will make it clear

    best,

    At the moment when we start getting error, we see this in log:

    this workload config should fix your issue
