error occured on line 58

An error occured on line 58 in file /home/.jamal/sdemon/sd.nickwood.ca/forums/include/dblayer/mysql.php.

PunBB reported: Unable to connect to MySQL server. MySQL reported: Unknown MySQL server host 'mysql.nickwood.ca' (1)

Now I've tried reading around to see if I could find the problem. Someone else had an error on line 58 but it was auth. this time it cant connect... anyone know?

****EDIT*******************************************

It wasnt anything to do with PunBB which I figured it wasnt. The host im one runs all SQL off their webservers to lower cpu usage so... fixed it
