If you checked https://kaosx.us/packages/mirrors.php for mirror status, then you are correct, the fosshost mirror shows as synced.
But that mirror uses Fastly to connect to some 20 mirrors around the world (that is why it is the default mirror). So there is a slight possibility you are connecting to a not syncing mirror. But before accepting that, a little more info is needed.
Post the complete /etc/pacman.d/mirrorlist and /etc/pacman.conf. Enclose the output of those files with 3 backticks (```) for readability. That is done for you now in the first post. And post the full output of the syncing error message you get.
To make sure it is not a bad local database, run sudo pacman -Syy to force a refreshing of the db.

    @drago merged into existing thread, see my first reply here for needed additional info.

      Sky I tried to replicate with a few installs, to see if something is wrong with fosshost, all good here, so it probably is a location issue.
      Just try a different mirror, best one close to you. Comment out the fosshost mirror (place a # in front of the Server line, like:

      # Server = https://mirrors.fossho.st/kaos/$repo

      then place the mirror you want to use as the first uncommented mirror. To update & force a new database, it will be good to update with sudo pacman -Syyuu

          demm So I did as you suggested and picked a different mirror (from the Netherlands this time) and it's now syncing but then it's offering to downgrade the knotification fix you posted a couple of days ago. Is this something I have to do just to be fully synced again and then later get the updates and the knotification fix back? thanks

          sudo pacman -Syyuu

            The uu part forces install of packages in the database only, thus the downgrade offering for knotification (it has not moved yet from the build repo, but will move shortly). Your choice to downgrade, or update with regular pacman -Syu now that you databases are properly synced. Even a regular update will give a warning that a local package is newer then repo, but you know why. Message will go away once knotification has moved & mirrors have synced.
