I already tested numerous solutions but none of them worked.
You can download source project Here .
The name of database is wrong. Check whether it is another name or case.
So I tried to fix the error myself but there is another one
Authentication to host 'localhost' for user 'root' using method 'caching_sha2_password' failed with message: Unknown database 'mysql80'
Your screenshot does not show that a database named mysql57
actually exists. The error message is correct: the database name you're trying to use is wrong.
Try changing to Database = brawldatabase;
in your connection string.
