[SOLVED] Proxmox DNS not resolving on Hetzner Dedicated Server

[rudidekok]

Below is what happens when i ping by name

PING google.com(fra24s04-in-x0e.1e100.net (2a00:1450:4001:827::200e)) 56 data bytes
^C
--- google.com ping statistics ---
176 packets transmitted, 0 received, 100% packet loss, time 179182ms

I know there is another option by purchasing an additional IP Address and saw a guide written on hetzner but honestly unsure of how to do it

/etc/network/interfaces:

auto lo
iface lo inet loopback
iface eno83xx inet manual

iface eno84xx inet manual

auto vmbr0
iface vmbr0 inet static
        address xx.xx.89.200/25
        gateway xx.xx.89.129
        bridge-ports eno8303
        bridge-stp off
        bridge-fd 0
        up sysctl -p

iface vmbr0 inet6 static
        address xxxx:xxx:xxx:xx43::2/64
        gateway xx80::1

auto vmbr1
iface vmbr1 inet static
        address 192.168.100.1/24
        bridge-ports none
        bridge-stp off
        bridge-fd 0
        post-up iptables -t -nat -A POSTROUTING -s '192.168.100.0/24' -o vmbr0 -j MASQUERADE
        post-down iptables -t -nat -D POSTROUTING -s '192.168.100.0/24' -o vmbr0 -j MASQUERADE
        post-up iptables -t raw -I fwbr+ -j CT --zone 1
        post-down iptables -t raw -D fwbr -j CT --zone 1

/etc/resolv.conf

nameserver 1.1.1.1
nameserver 1.0.0.1
nameserver 8.8.8.8
nameserver 8.8.4.4

Also to note these are both uncommented
/etc/sysctl.conf

net.ipv4.ip_forward=1
net.ipv6.conf.all.forwarding=1

Hi
Thank you for responding.
I managed to get it working a few minutes ago by simply removing ipv6 from the gateway from iface vmbr0
