cPanel MySQL, Database Err: SQLSTATE[HY000] [1044] Access denied for user ‘MySQL DB name’ to database ‘MySQL user name’

I applied a free domina xxx.freewebhostforyou.ml
then i uploaded my sites files through ftp,
when i comleted the mysql set, then came to

Database Err: SQLSTATE[HY000] [1044] Access denied for user ‘htofo_30627431’@’192.168.%’ to database ‘htofo_30627431’

This is my MySQL setting
‘htofo_30627431’@’192.168.%’ is ‘htofo_30627431’@’local%’,
but where is ‘htofo_30627431_yang’ I set?

Since it is a free host/domina， it doesn’t support SSH.

How should solve it in MySql of cPanel?

Tks
