Error installer.php can’t find archive

Good day

We are trying to overwrite an existing website with a new one using Duplicator. We made two packages (one installer and one archive) and installed them in the root of the website (www.zelfbeschadiging.nl)

Now when we want to start install, the following error occurred:

—
Setup Notice:
An error has occurred. In order to load the full installer please resolve the issue below.
Archive not found! The ‘Required File’ below should be present in the ‘Extraction Path’. The archive file name must be the exact name of the archive file placed in the extraction path character for character.

If the file does not have the correct name then rename it to the ‘Required File’ below. When downloading the package files make sure both files are from the same package line in the packages view. If the archive is not finished downloading please wait for it to complete.

If this message continues even with a valid archive file, consider clearing your browsers cache and refreshing, trying another browser or change the browsers URL from http to https or vice versa.

Extraction Path: /www/

Server Settings:
ZipArchive: Enabled
ShellExec Unzip: Disabled
Extraction Path: /www
Installer Path: /www/dup-installer
Archive Name: [HASH]_archive.zip or [HASH]_archive.daf
This is based on the format used to build the archive
Archive Size: Expected Size: 683.03MB Actual Size: 0B
Boot Log dup-installer-bootlog__[HASH].txt

Please Note: Either ZipArchive or Shell Exec will need to be enabled for the installer to run automatically otherwise a manual extraction will need to be performed. In order to run the installer manually follow the instructions to manually extract before running the installer.

The strange thing is that we installed both files on the same spot? Another strange issue (which I can’t wrap my around) is that the ftp url is different to the website url. What can we do to fix this issue?
