Need help with mysql

[EvilToast]

When I try to login to the admin panel I got this:
Warning: mysqli::mysqli() [http://testit.netne.net/android/mysqli.mysqli]: (HY000/1130): Host '31.170.160.169' is not allowed to connect to this MySQL server in /home/a1601680/public_html/android/admin.php on line 11

Line 11 - 14 from admin.php:
