Reconnection when there is a network outage at the startup of the application

When there is a network outage, Rainbow does not start. Quiet normal. 

But then, there is only one option : "cancel". The application does not suggest to reconnect, or keep reconnecting until the network is back (for example, make a try every 30 sec). 
the user will quit the application, and eventually will stop using the application. 
My suggestion is to do something similar to teamviewer. if network i down, it will keep reconnecting. 
If the remote host is disconnected, it will keep reconnecting or suggest the user to make a manual reconnection.
