I have successfully connected to my remote (iMac) computer on Team Viewer, but every week, after a few days, the remote computer goes off line. I have checked all of the settings, including the one that allows me to wake up the remote computer, but the remote computer remains off line. I am running the most up-to-date (free) version of Team Viewer on my local and remote Macs/OS Catalina) Any ideas on how to fix this?
