install works now, but i get queryNs ECANCELLED error ubuntu 18.04

[linuxpowerhouse]

okay, so i solved my issue on installing by going back to ubuntu 18.04, but now i have ran into a new issue.

i am stil on ubuntu 18.04 and when i get to the main page of the startup where it ask for my domain name it gives me this erro

queryNs ECANCELLED , or it gives me the cannot find nameservers.

i have looked thought the docs and seen others have the same issue (only two) where they run the host NS -t command for my domain and it wont resolve it,

but on my pc it will.

and the the server it will not resolve my domain but it will resolve others IE facebook.com which is very strange. if anyone could give some direction i would appreciate it.
