Thanks to @amin I now have a second host for my blog, so it's now also available at https://sotolf.polymaths.page will be nice for the times that codeberg is down ;)
it turned out in the end it wasn't that tricky to set up
basically just adding
rsync -av --exclude .git -e ssh ~/hugo/public/ sotolf@polymaths.page:~/sotolf.polymaths.page/
into my publish script and it seems like it works, and should be updated in the future as well :) nice
