posting so it doesn't get lost.

bisect: https://pastie.io/cbqedk.txt

" To reproduce in Unity 2021, build and run Basic example as dedicated server, build as client, try to launch multiple clients. 1st client is always fine, 2nd client always fails to connect, whether built client or playing client in editor after you have first one connected. "

server can be headless or normal, host client or server only...I did the bisect with headless out of convenience.

Ok I can reproduce it on mac.

tanks demo + kcp V1.22

• first build = server-only
• second build = client: works
• editor = client: see error in console (may need to connect a couple of times to trigger it)
