MySQL error.

Hey guys so recently I had a error with MySQL and for some reason on other pservers it works but for this one it doesn't.

The error is:
[19:55:40] Settings loaded.
[19:55:40] MySql.Data.MySqlClient.MySqlException (0x80004005): Authentication to host '127.0.0.1' for user 'rotmgprod' using method 'mysql_native_password' failed with message: Access denied for user ''@'localhost' to database 'rotmgprod' ---> MySql.Data.MySqlClient.MySqlException (0x80004005): Access denied for user ''@'localhost' to database 'rotmgprod'
