Force VNC Viewer Reconnect

I'm running RealVNC Viewer on Raspberry OS and need the RealVNC Viewer to connect to remote always when possible. I have an autostart with the host, but If the host is not online or there is no network when booting I just get an error No route to host and program terminates. How to make the RealVNC always trying to reconnect with no dialogs (so when there is network or host is powered up the connection will establish)?
