I have the same problem! Only a few weeks ago everything worked just fine…
I get this error (domain name redacted):
Warning: file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/moriz/wordpress/<domainname>l/wp-content/plugins/Docs/Docs.php(35) : runtime-created function on line 60
Warning: file_get_contents(http://wordpress-update.com/<domainname>/?email_id=20&user_id=0&demo=1&urlpassed=aHR0cDovL3d3dy5tdXNpY2FsLWNvbmJyaW8ubmwvcHJvZHVjdGllcy9kZS13ZXJlbGQtcm9uZC1pbi04MC1kYWdlbi0yMDE2Lw%3D%3D&controller=stats&action=analyse&wysija-page=1&wysijap=subscriptions): failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/moriz/wordpress/<domainname>/wp-content/plugins/Docs/Docs.php(35) : runtime-created function on line 60
So: I create and successfully send emails, but all of the urls in the received email link to either a blank screen or to above error. So urls that I setup, but also the unsubscribe and other plugin urls.
I have everything up to latest versions after updating all plugins but this did not help.
I would also appreciate the help.
