Turns out that the second server of where i would like to import the site, there is some sort of new firewall installed on DirectAdmin, which only allows to use ports 35000-35999 or something. They're looking for a solution now.
Thanks for guiding me in that direction! Let's hope they solve it, so I can use the import option again.
