I think the reason is this:
i start client and server in awake method on custom script;
NetworkManager not initialized yet;
error

Anyway, NetworkManager dont have any events like "OnInitialized", or propertys like "IsInitialized".
And I can't find out when the client or server can be started, this seems to be the root of the problem.

The NetworkManager should be safe to start in the Start method, however we don't suggest this approach. We suggest you have some UI menu where your players must click a button in order to connect to the network.
