This is strange if nothing else happens, the code running there is https://git.cloudron.io/cloudron/box/-/blob/master/scripts/installer.sh?ref_type=heads#L126 so its not doing much but downloading nodejs and some extra filesystem things.
Can you curl or curl -sL https://nodejs.org/dist/v18.16.0/node-v18.16.0-linux-x64.tar.gz ?
