Debian on Virtual Mips Malta platform

I am trying to run Debian on MipsMalta platform which is emulated by OVP . The problem is that the setup tool needs to download files from Debian mirrors but it cannot proceed in downloading files, I tried many different mirrors from different countries, but I get the following message: > The installer failed to download a file from the mirror. This maybe a > problem from your network, or with the mirror. You can choose to retry > to download, select a different mirror, or cancel and choose another > installation method. I also changed the default Debian Installer embedded in OVP with the one available here: http://ftp.nl.debian.org/debian/dists/jessie/main/installer-mipsel/current/images/malta/netboot/ but the same message appears. Obviously, this method of installation is based on netboot. Do you know where exactly can I find the required files for offline method of installation, in case the netboot version is not fixed?
