[SceneEventData- Scene Handle Mismatch] serverSceneHandle could not be found in ServerSceneHandleToClientSceneHandle.

Hello, im kind of new to Unity, what does the warning above mean?
It logs every time on client side whenever host changes scene.
I’m using Netcode for GameObjects with Unity Transport.

I would guess it means that you are not sending your scenechange over to other clients when you change the scene on your host. Remember, EVERYTHING in multiplayer needs to undergo handshakes back and forth. Imagine there’s 1 host and 20 connecting clients. If 1 client needs to undergo a change then it needs to handshake and inform the host of a change, then the host needs to send this message back to all the other 19 clients. If multiplayer is your interest, keep doing it. If not then I suggest starting with making a singleplayer game first. Multiplayer is biiiiiiiig and requires alot of work, and I mean ALOT of work. It should be the last thing you work on if you are new to unity and coding. Just my tip from someone who had big plans but found out the hard way.

Hi, i have the same problem now, did you end up finding a solution for this?
Thanks.

Seems like this was caused by Network Object components on canvas elements. By now, I removed them (that also removed the warning).
