SQLSTATE [HY000] [1045]用户'root'@'localhost'的访问被拒绝(使用密码:否)(SQL:从“权限"中选择*)

我将项目上传到C-panel上，并在我的 env 文件中设置了数据库连接，使用相同的设置对我来说还可以，但是现在我不知道为什么会发生这种情况，这是错误的:

I upload my project on C-panel and set my connection for database in my env file, it was ok for me with the same settings, but now i don't know why it's happening, this is error :

SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) (SQL: select * 
from `permissions`)

这是我的 env 数据库文件设置:

And this is my env file settings for database :

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=thermota_db
DB_USERNAME=thermota_user
DB_PASSWORD= { my password }

我不知道此权限有误，是我的Permissions_table吗?

i don't know this permissions in error, is my permissions_table ?

为什么此表出错?
