Got error.ConnectionResetByPeer on receive. This indicates that a previous message did not find a valid destination.

I will investigate how to reproduce it soon. Found while working on SBBs. Not sure if save matters, including in case it does.

That's weird. This means that your operating system cleaned up the network connection before the other side received the disconnect signal (which is sent before closing the socket).

I should have mentioned that this is on Windows 11, I get this consistently when leaving local worlds.

Alright, so previously the disconnect function would wait for a total of 30 ms after sending the disconnect signal before closing the socket.
So I guess we could just reintroduce some delay. Could check if adding this code in network.zig helps?

Yes, after that change I was not able to reproduce the error anymore.

Add a delay before after sending the disconnect signal on windows loc…

@IntegratedQuantum

@IntegratedQuantum I keep getting the error. I didn't in 3.0 but it did start a while ago. It may have started after This PR
@Argmaster Are you getting this again?

I saw it, but it might have been when I was ungracefully closing the game, I have to double check.

Please make a new issue then.
