To verify if the discovery issue is on android viewer app, could you please try to connect using HTML5 Viewer on your non working devices (e.g. Pixel 3).
Just open a web browser (e.g. google chrome) then go to http://viewer.spacedesk.net/, then type the IP address of your primary machine to connect.
Looking forward to your feedback.
