ping unknown host google.com

I have 4 servers setup with forge, on two i can ping google fine. But on the other two i get: unknown host google.com

both working and not working server look identical

/etc/resolve.conf

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8
nameserver 8.8.4.4

pinging the ip works on all

Can someone point me in the right direction?

Thank you

Try dig google.com (you might have to install 'dnsutils' first - not sure). That should try and do a lookup but also show the name of the dns server it tried to use. If it doesn't come back with a sensible result try dig @8.8.8.8 google.com and see what that does (it makes the tool ignore your local dns settings and query 8.8.8.8 direct).
