Description

A clear and concise description of what the bug is.

User1 makes a server and is the host. When User2 joins the server using the room code, this error appears:

[Netcode] Received a packet with an invalid Hash Value. Please report this to the Netcode for GameObjects team at https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/issues and include the following data: Received Hash: 2450266271307143725, Calculated Hash: 4077705673384003339, Offset: 4, Size: 112, Full receive array: 70 00 00 00 60 11 01 00 70 00 00 00 2d 1a 62 12 31 18 01 22 09 d2 02 02 01 7d 9a e2 a5 01 b2 36 17 b3 01 46 c4 ca 04 01 39 3b e8 2c 01 ab c9 50 60 01 53 a3 38 44 01 d3 f6 1c b8 01 a6 22 89 97 01 b5 fe 01 74 01 be 97 be 73 01 9d 9a 5c 01 01 e9 51 97 17 01 8a f7 e7 83 01 42 7f 88 c6 01 97 a3 f5 46 01 00 00 00 00 01 e7 1d 78 79 e7 4f 92 6d 00 00 00

Reproduce Steps

  1. User1 creates a server by calling StartHost() and receives a room code.
  2. User2 joins the room by typing in the room code and calling StartClient().
  3. When User2 is joining the server, the error occurs on the host-side.

Actual Outcome

A clear and concise description of what happened and broke.

User1 created a server by calling the StartHost() function. They are sent to a server and provided with the room code. User2 joins the server by typing in the correct room code. When they call the StartClient() function, the client attempts to join the server and is waiting to join. On the Host side (User1), the error appears and enters Pause mode in Unity.

Expected Outcome

A clear and concise description of what you expected to happen.

User2 should be able to join the server without error.

Hi @alex4101, thank you for letting us know about this issue.

To better understand the nature of the issue, can you provide us the transport protocol you are using for your project?

If your project is not using UTP (com.unity.transport), can you try it with UTP and see if you are still encountering this issue?
