Players getting disconnected while playing game, with error "error sending buffer channel : 1 ..." and"Client disconnect error : timeout" kindly configure settings for my unet multiplayer game to solve the disconnect issue. probably my bandwidth exceeding the unity per player bandwidth of 4K. so if u know what im talking about and can help me solve this disconnect you can connect via teamviewer and check the issue. Please bid only if you have UNET unity multiplayer services experience.
