Cannot resolve host address

[arjones85]

nslookup for my VPN provider is not working, but nslookup for everything else seems to work just fine. This address does exist and resolves fine on any other box. Could use some help understanding what is going wrong. Thanks!

docker run -it --cap-add=NET_ADMIN --device /dev/net/tun --name vpn --dns 8.8.8.8 -v /root/vpn:/vpn -d dperson/openvpn-client

[root@jonesmedia compose]# docker exec -it vpn sh / # nslookup us-dal.secureconnect.me Server: 8.8.8.8 Address: 8.8.8.8:53
