Welcome,
I am using Syncthing to Sync Folders from 3 Debian Hosts to each other. On my first host all files are up to date, but the 2nd and 3rd got a problem with synchronizing from 1st.
It tells me there are Out of Sync Items but If I view the list, and check on the host, the file already exists and is up to Date
I am experiencing this by syncing /var/lib/docker/volumes
.
