RPiOS native VNC server disconnects from Cloud

Hi, I shuttle between two homes 1,000 kms apart; a couple of RPis in both locations monitor temperature, energy consumption, central heating performance etc. All RPis act as VNC servers and I can monitor the data in one location from a VNC viewer in the other. However for a number of reasons--RealVNC Cloud servers are down, or  internet disruption at home--the connection between RPis and Cloud occasionally breaks down and can only be restored by rebooting the RPis in the remote location ... during my next travel there. Until then I have no longer access to the remote data.

Is there a way for the VNC server to reconnect automatically after a temporary disruption of its link to the Cloud? It may be more an RPi or Debian than a VNC issue, as a matter of fact.

Thanks
