An error occured while attempting to connect to the database: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.  
  
  
  
and if I change DB ip to name got following error  
  
  
  
An error occured while attempting to connect to the database: SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client  
  
  
  
My Server Configuration is

IIS - 8.5  
  
PHP - 5.6  
  
MySQL - 5.5
