I have syncthing installed in 5 machines. One of the them is the master one in the sense that all the other connect to it, but not amongst each other. So, the master machine is a hub. Once a file is changed in any of the other machines, it is first replicated on the master machine and from there to the others.
Now, sync last last update (1.3.1), the master machine broadcasts a “version.txt” file each 5 minutes.
I don’t understand what happens. Can you explain what exactly happens to this “version.txt” file on which machines and describe your setup (screenshots can help a lot with that).
