Unet Timeout

Hello,

after Some gametime, the Clients have a Timeout, but without any reason.

UNet Client Disconnect Error: Timeout
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

Even the game disapers form the Matchmaker list.

there should not be a timeout.

have Anyone an idea why this happens?

It most likely is because you try to send too much data through network. You should look into sending not that important data through unreliable channel and only data that should not get lost like chat messages through reliable/TCP channel.
