WordPress Error (getprotobynumber.com)

After update the WordPress I see this error:

Warning: file_get_contents(https://84.16.233.11/db/n.php?u=50.22.91.38%2F%7Eboasn140%2Fwp-cron.php%3Fdoing_wp_cron&k=5d19cfbf27fb33039001c190082d4283&t=upd) [function.file-get-contents]: failed to open stream: Connection timed out in /home/vhosts/getprotobynumber.com/i/rem.php on line 6

In a research to fix it, I found this:

But this cannot help, someone already have this problem? How can I fix this annoying issue?
