Re : Facing issues while connecting to retail_dba

I am facing the below issue while connecting to retail_dba
ERROR 1045 (28000): Access denied for user ‘retail_dba’@‘gw01.itversity.com’ (using password: NO)

Can someone please guide me on this.

Also checked the below :
telnet nn01.itversity.com 3306
got the response as:

Escape character is ‘^]’.
