Plex media server recently started disconnecting from the main plex servers periodically

Server Version#:4.159.0
Player Version#: Not applicable
Recently (started somewhere in the last month) the plex media server disconnects from the main plex server and all the plex player applications say they cannot get data from the media server. I then need to restart the plex app on my server to regain the connection. This is fine when I am at my house, but I travel. Is this a recent bug in the plex media server? Is there a way to stop this from happening?
