Following a warning on sshfs backup failures yesterday, I tried to initiate a backup manually with plinth, it did not work.
I rebooted, tried again, it worked and then there was an automatic backup the same day and in the night for the next day.
In case it is of any use, here is what the journal shows:

There was apparently a reattempt every hour, the error messages look the same (but I did not check in detail).
