Network Messages/voids, help?

Is there any message/void for when a client joins a server, but the server does not exist(because of an outdated refresh or slow connection)?

Also is there any message for when deploying a server fails, like another server has the name, or something?

Thanks.

Unity - Scripting API: Network scroll to the bottom and read the messages.

Edit: and next time use Google :slight_smile: it was the top hit for the term: network unity
