file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known
It means your server cannot connect to the outside world
This probably won't change anything given the DNS issues
So, If you have permission, try changing the name servers in your /etc/resolv.conf file to other nameservers.
There should be as well httpd allowed to connect outside. Check you selinux policy.this helps me to solve connection problem:
setsebool -P nis_enabled 1setsebool -P httpd_can_network_connect 1
In reference to one of the comments by @DUzun, and for those like myself who are familiar with the server in general but not a computer science major, I fixed the issue on Linux/Centos6 (Plesk Onyx) by:
1) Opening /etc/resolv.conf (my file was empty)
2) Added:
nameserver 8.8.8.8nameserver 8.8.4.4options rotateoptions timeout:3Hopefully this helps someone out there.
