Question Exception "KeyNotFoundException: The given key '4294967296' was not present in the dictionary"

&
"A lot of pipeline updates have been queued, possibly too many being scheduled in pipeline logic, queue count: 0"


I've been running a host on the editor, and a client on a build in order to test what would happen when the host's app/game is not running while in mid-game. To do so, I stop the game on the editor for a couple of seconds (2s - 15s approx), and the client was waiting for the host to come back. So far so good, as this is the intended behavior. As soon as I resumed the editor, both the host and the client resumed their game and everything worked fine.

However, I stopped the game one more time for like 30s or so, and I got these errors on the Editor (host):



If I'm not mistaken, this means that the host (because it's got ID = 0) disconnected from the game.





And finally this warning:



For this last warning, I was getting 1 warning per frame, and it doesn't stop.

I have no clue what these exceptions/warnings mean, so I'll appreciate any help. Thank you.

 

You can increase the time out by changing the Unity Transport's Disconnect timeout MS field in the inspector, but I don't know if there are any consequences with this. Presumably there's going to be a build up of messages to send until the connection is re-established. It's a good idea to subscribe to NetworkManager.Singleton.OnClientDisconnectCallback on both client and server so you can do the clean up should the client be disconnected.

I don't know about the errors but to rule out something that's already been fixed update to the latest version of Netcode.
