PHP error: php_network_getaddresses: getaddrinfo failed: (while getting information from other site.)

Question

Trying to get information from an external source, I'm receiving the following error:

Warning: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in line #...

Yesterday everything was fine, so what happened to this script, which is not working and gives me the error above? Any solution or hint to solve this problem?

$uri = "http://api.hostip.info/?ip=$ip&position=true";

$dom->load($uri);

I also tried by converting DNS to IP but then I get the warning: failed to open

$uri = "174.129.200.54/?ip=$ip&position=true";

I tried to remove the http but am still getting the above error.

Answer 1

i don't know but i am using adminer pulled from docker

and Server is

mysql

route like

http://localhost:8080/?server=mysql&username=root

Answer 2

if you using docker containers then add socket in MySQL configuration, it solved my issue unix_socket=/Applications/MAMP/tmp/mysql/mysql.sock

Answer 3

The resolvers are having issues. The resolvers are specified in the /etc/resolv.conf file and are set based on the network configuration scripts on the Droplet. These are populated by the initial deployment configuration cloud-init system.

Solution 1:
You can add nameserver in this file: /etc/resolv.conf

nameserver 127.0.0.53
options edns0

Solution 2:
We need to specify a remote DNS server as our global, system-wide DNS server. We can do this in this file : /etc/systemd/resolved.conf

[Resolve]
DNS=8.8.8.8 8.8.4.4 2001:4860:4860::8888 2001:4860:4860::8844

And Then reload configuration and restart services:

sudo systemctl daemon-reload
sudo systemctl restart systemd-networkd
sudo systemctl restart systemd-resolved

After Storage Full I have freed up space, No Install commands are working like apt-get update, and also PHP file_get_contents() and curl() also not working. The 2nd Solution worked for me on the ubuntu Server.

Answer 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.

Answer 5

I faced this issue, while connecting DB, the variable to connect to db was not defined.

Cause: php tried to connect to the db with undefined variable for db host (localhost/127.0.0.1/... any other ip or domain) but failed to trace the domain.

Solution: Make sure the db host is properly defined.

Answer 6

I think that you should try replacing php7.3-curl with api.hostip.info/?ip=$ip&position=true . Hope this helps

Answer 7

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

Answer 8

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&position=true";

Use $uri = "api.hostip.info/?ip=$ip&position=true";

And it worked fine afterwards

Answer 9

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.

Answer 10

In my case(my machine is ubuntu 16), I append /etc/resolvconf/resolv.conf.d/base file by adding below ns lines.

nameserver 8.8.8.8
nameserver 4.2.2.1
nameserver 2001:4860:4860::8844
nameserver 2001:4860:4860::8888

then run the update script,

resolvconf -u

Answer 11

In the following httpd.conf file, configure the ServerName properly.

/etc/httpd/conf/httpd.conf

Like below:

ServerName 127.0.0.1:80

or

ServerName sitename

This resolved similar issue I was facing.

Answer 12

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.

Answer 13

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...

Answer 14

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
