Updater fails: unable to resolve host address 'repo.turris.cz'

Hello,
I have got the same issue while trying to get my Omnia turris even going.
I have flashed to the newest version with USB

root@turris:~# cat /etc/turris-version
3.10.3

Windows 10, Provider is NetBox in Brno - I kind of think that might be the cause

These are the errors I have so far, trying different methods found here on the forum.

This is on my basic settings page

Same as with OPKG update

root@turris:~# opkg update

I thought it might be certificate as well, but with no succes either

root@turris:~# wget http://repo.turris.cz/omnia/packages/base/ca-certificates_20170717_mvebu.ipk
