Description

When hosting a relay, an error message popped up which asked me to report it here :)

Error message;

[Netcode] A ConnectionRequestMessage was received from the server on the client side. NetworkTransport: Unity.Netcode.Transports.UTP.UnityTransport UnityTransportProtocol: RelayUnityTransport.

Reproduce Steps

I'm honestly not sure how to reproduce it. I hope the error message alone helps. This error occurred on the server and all clients were unable to connect.

Actual Outcome

A clear and concise description of what happened and broke.

Expected Outcome

For all clients to be able to join

Screenshots

This error was also thrown, I have never seen it previously so it might be related, but I don't know.

Environment

• OS: Windows 11
• Unity Version: 60000.0.23f1
• Netcode Version: 2.1.1
• Netcode Commit: Current NGO release on the package manager

Additional Context

I'm happy to provide any details you need upon request, but I have honestly no clue where this is coming so I wouldnt know what to even include here.

I hope this helps, thanks!

Were you just using UnityTransport or a different transport when you got this error message?

[Mesaying]

I am only using Unity transport, the error particularly occurs when a client leaves a game (relay) and then tries to create another one. Though that might just be down to my implementation, not sure
