Bug Unity Relay bugs: RelayServerData not secure, allocation key incorrect byte length

    I'm using Unity's Transport with the Relay and Lobby systems.

    When I opened my projects today, they suddenly stopped working. I haven't touched the code, and every game I've made with this system suddenly has the same bug, even though the code varies drastically game to game.

    I have the following code:
    Code (CSharp):
    1.         JoinAllocation joinAllocation = await RelayService.Instance.JoinAllocationAsync(joinCode);
    2.         transport.SetRelayServerData(new RelayServerData(joinAllocation, "dtls"));
    3.  
    I then attempt to join the lobby as a client--however, the connection fails. After searching through old unity relay forum threads, I wondered if the problem was that Unity Relay was stopping the connection because it wasn't considered secure, which is a bug that has occurred for other users in the past. The solution is to manually set the relayserverdata.isSecure to true. So, I altered the code:

    Code (CSharp):
    1.         JoinAllocation joinAllocation = await RelayService.Instance.JoinAllocationAsync(joinCode);
    2.         transport.SetRelayServerData(new RelayServerData(joinAllocation.RelayServer.IpV4, (ushort)joinAllocation.RelayServer.Port, joinAllocation.AllocationIdBytes, joinAllocation.Key, joinAllocation.ConnectionData, joinAllocation.HostConnectionData, true));
    3.  
    using this documentation as a guide:
    https://docs.unity3d.com/Packages/c...utp@1.0/api/Unity.Netcode.UnityTransport.html

    I don't yet know if this change fixed the bug, since I was met with another bug:

    The JoinAllocation's Key is apparently the wrong byte length, causing SetRelayServerData to fail.

    I think this approach is better. Also could you share Relay and Lobby versions?

    I should have the latest versions of both--Relay is 1.0.5, Lobby is 1.0.3

    That approach works fine normally, except that there is no way to set allocation.isSecure using that method, unless I'm missing something?
