MySQL 8.3 Release Notes
If you get the following error, it means that when
mysqld was started or when it reloaded the
grant tables, it found an account in the
user table that had an invalid password.
Found wrong password for user
'
some_user'@'some_host';
ignoring user
As a result, the account is simply ignored by the permission system. To fix this problem, assign a new, valid password to the account.
