Although this is a old thread  I have come across the same error recently while running nslookup in CentOS 7 and google search led me to some of the discussions in SO including this one  However  adding the nameservers entries to  etc resolv conf alone did not help as the nameserver values in resolv conf were overwritten by the NetworkManager with the default DNS nameservers that are in the eth profile associated to the ethernet IP config   As mentioned by  m-canvar  set the following entries in  etc resolv conf  search yourdomain com nameserver 8 8 8 8 nameserver 4 2 2 1 nameserver 8 8 4 4   To prevent overwriting these entries by NetworkManager  there are two two approaches   Option 1  Either set NM CONTROLLED no in the eth profile associated to the IPv4 IPv6 profile   Option 2  Disable NetworkManager service from running   chkconfig NetworkManager off service NetworkManager stop   More details can be referred in my post about this error and solution

In my case this was being issued by wp cli  and the problem was that I didn t have php7 3-curl installed  Fixed with  apt-get install -y --quiet php7 3-curl

It s because you can t resolve the host name Maybe DNS problems  host is unreachable     try to use IP address instead of host name    ping this host name    nslookup it

If you can discount transient outages on the remote server you are trying to connect to  then that just leaves the local network config as a problem    Using the IP address instead of the hostname is only going to work for the default domain on the remote host   What happens when you try using www google com  or its IP address   If you stil can t connect  then its something to do with the network between your server and the outside world

I would imagine that the caching DNS servers you re using aren t behaving properly  or the DNS server for the domain you re resolving isn t working properly    You can try to fix the former possibility   Do you have at least 2 name servers registered on your network adapter   You could always swap your computer over to use a different caching DNS server to rule this out   Try Google s   8 8 8 8 8 8 4 4

I faced a similar issue on Docker for Ubuntu  It s a DNS issue  You will have to add Google Public DNS Settings into your network  Instruction for adding those settings is OS dependant  In my case  I was using Ubuntu so I added via network manager  Visit this site for more info

Although I didn t use this exact function I got this same error   In my case I just had to remove the protocol   Instead of  uri    http   api hostip info  ip  ip amp position true    Use  uri    api hostip info  ip  ip amp position true    And it worked fine afterwards
