problem with update (no replies)

hello my problem seems odd
I connect to my remote database with jdbc
a problem occurs during update
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: UPDATE command denied to user 'ramitnco_root' @ '41 .227.205.64 '; for table' connected '
but it's not a privileges problem because the user ramitnco_root have all privileges.
I can do update using mysql query browser whith same user same adress
and I can do update when I work with my database locally
