retry connecting hosts in multi screen setup

[tobexyz]

Hi, when I am restarting a secondary display the instance is waiting for a connection but the main instance won't reconnect the secondary display. I've to restart the main instance in order to initiate the startup process. This also happens if the secondary display did not receive the udp message during startup due to network issues.

As far as I understand the main instance is trying to reach the configured secondary hosts during startup

If the host can't be reached it will be ignored I think.

Is it possible to retry connecting the peers during the main loop before starting the update routine?
