though i have changed the database name , user and password in .env file it still says "Access denied for user 'root'@'localhost' (using password: NO)" which was my localhost password and user name''

I couldnt even clear my cache

while i was try to use following code on server

php artisan cache:clear
php artisan config:clear
php artisan config:cache
php artisan view:clear

the following error was shown on the terminal

[In Connection.php line 664:

SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using pas
sword: NO) (SQL: select * from rooms order by order_by asc)

In Connector.php line 70:

I also faced this issue, every thing is fine your DB_USERNAME or DB_PASSWORD, if you your password string contains # (for eg. Test123#) "feature"of 5.8 or above it treat # as comment delimiter, so rewrite your password as DB_PASSWORD='Test123#' and its works. it work for me.

It's due to caching. so delete cache file 'config.php' from bootstrap/cache/config.php . Thanks

I have encountered the same error. SQLSTATE[HY000] [1045] Access denied for user 'niyo'@'localhost' (using password: NO)

I found that I did not create user called niyo and grant to him all privileges. I configured it in user accounts section of PhpMyAdmin interface.

.env file sample

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=oneagentdb
DB_USERNAME=niyo
DB_PASSWORD=123456
