Hello,

I just made a reboot on my server and now DNS doesn’t seem to be working, I’ve googled to see if I could find some answers but nothing has helped so far, So I hope there is a friendly person here that can help me.

ifconfig -a

/etc/resolv.conf is empty

/etc/network/interfaces.d/50-cloud-init.cfg:

auto lo
iface lo inet loopback
    dns-nameservers 8.8.8.8 8.8.4.4

auto eth0
iface eth0 inet static
    address 165.227.170.***
    gateway 165.227.160.1
    netmask 255.255.240.0

# control-alias eth0
iface eth0 inet6 static
    address 2A03:B0C0:0003:00D0:0000:0000:0018:A001/64
    gateway 2A03:B0C0:0003:00D0:0000:0000:0000:0001

# control-alias eth0
iface eth0 inet static
    address 10.19.0.7
    netmask 255.255.0.0

auto eth1
iface eth1 inet static
    address 10.135.7.***
    netmask 255.255.0.0

/etc/network/interfaces:

auto lo
iface lo inet loopback

source /etc/network/interfaces.d/*

what happens to /etc/resolv.conf after running
resolveconf -u
?
