Laravel Access denied for database user - laravel

Question

I've created a MySQL user, granted privileges, and a database:
mysql> CREATE USER 'karaoke'#'localhost' IDENTIFIED BY '86v#...';
Query OK, 0 rows affected (0.05 sec)
mysql> GRANT ALL PRIVILEGES ON *.* TO 'karaoke'#'localhost';
Query OK, 0 rows affected (0.04 sec)
mysql> FLUSH PRIVILEGES;
$ mysql -ukaraoke -h localhost -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
...
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| karaoke |
+--------------------+
2 rows in set (0.01 sec)
mysql> use karaoke;
Database changed
mysql> show tables;
Empty set (0.01 sec)
I've updated my .env file with the db credentials:
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=karaoke
DB_USERNAME=karaoke
DB_PASSWORD=86v#...
However, when I try to run my migrations, I get the following error:
$ php artisan migrate
Illuminate\Database\QueryException
SQLSTATE[HY000] [1045] Access denied for user 'karaoke'#'localhost' (using password: YES) (SQL: select * from information_schema.tables where table_schema = karaoke and table_name = migrations and table_type = 'BASE TABLE')

What's gone wrong? I can login as karaoke user from the command line, but Laravel is having issues.
