You need to check if the username and password is correct. If they do, then the next thing to check is if that username/password has access from offshore1.x12host.com.
One way to do this (modify the command below to match your needs) is to run this command on MySQL:
Code:
GRANT ALL PRIVILEGES ON *.* TO 'dreamare_doc'@'offshore1.x12host.com' IDENTIFIED BY 'some_password';
