anyone?

I get errors for including extern.php?action=online, why could this be? i followed the instructions in extern.php and included it, double-checked the code & the address (my address = my URL, replaced for this post).

"Warning: main(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /(my-address) on line 43

Warning: main(http://(my-address)/extern.php?action=active): failed to open stream: Success in /(my-address) on line 43
