SessionException: Unexpected exception processing network metadata when client joins session while host starts Relay

Multiplayer Services

-

*Client scripts attached to ticket
Steps to reproduce:

  1. Host creates a Session without {{WithRelayNetwork()}} (solo lobby, no networking)
  2. A second client joins the session via join code
  3. Host calls {{StartRelayNetworkAsync()}} when player count >= 2
  4. Client intermittently fails during network metadata processin

Actual results:

Client throws {{SessionException: Unexpected exception processing network metadata}} (~2/10 attempts). Inner exception shows "Joining network failed." No identifiable timing pattern.

Expected results: 

Client successfully processes relay network metadata and connects without error.

Reproducible with versions: Unity 6000.0.58f2 and com.unity.services.multiplayer@1.2.1

  1. Resolution Note:

    Thank you for reporting a bug to Unity.

    Our investigation indicates the issue originates from a third-party asset, plugin, or service, rather than Unity itself. Because the problem lies outside our codebase, we're unable to address it directly.

    We will close this case as a third-party issue. We recommend contacting the vendor or maintainer for support. If you have evidence that the issue is within Unity, please share it and we will re-open the investigation.
