I have just updated Minisatip on a Pi4 to the latest version but the backend SAT/IP system will not connect anymore. I have raised a topic on the forum https://forum.mythtv.org/viewtopic.php?f=36&t=5841 <https://forum.mythtv.org/viewtopic.php?f=36&t=5841>. I would advise against anybody else updating.
