Hi all,
Not sure if it is relevant, but I have often had this problem, and it has always been from an orphaned syncthing process. I.e, the user login session which has my guix home services running in it ends, but the syncthing process is not terminated. Then I start a new login, and it tries to start a NEW syncthing service, and gives this same error. You can check this (next time syncthing fails to start) with: ps -e | grep syncthing Hope this helps, Zacchae
