DisconnectReason is empty when using Facepunch Transport

[cantaspinar]

Unity 2021.3.14f1
Netcode for GameObjects 1.2.0

NetworkManager.Singleton.DisconnectReason returns an empty string when using response.Reason in the ApprovalCheck or NetworkManager.Singleton.DisconnectClient(clientId, "reason").

Also, after 10 seconds from the client rejection, I get this error:

KeyNotFoundException: The given key '1' was not present in the dictionary.

Thanks to @NoelStephensUnity , a quick fix is here for getting the DisconnectReason on the client side.

Also, there is a pr on the way to handle the timeout exception.
