SQLSTATE[HY000] [1045] Access denied for user 'bluexyz_marketnew'@'localhost'

Hi, I'm getting the following error

Illuminate\Database\QueryException
SQLSTATE[HY000] [1045] Access denied for user 'bluexyz_marketnew'@'localhost' (using password: YES) (SQL: select * from `sessions` where `id` = WNbkwFbho2vfuuZyZSu4Uf2lCrnBLIJWH9eTBvST limit 1)

Please help me to resolve this.

I'm using shared hosting, I have uploaded the files after clear the cache still I got this error session table is not updated, is there any other ways to clear the cache.

Thank you
