Connecting to remote mysql database - aws server

I have created a user in mysql database like this:

create user 'remote'@'localhost' identified by 'myUserPassword';
grant all on *.* to 'remote'@'localhost';
flush privileges;

create user 'remote'@'%' identified by 'myUserPassword';
grant all on *.* to 'remote'@'%';
flush privileges;

When I try to access it using heidi, I am getting this issue. I have done this before and I can access other servers easily using my newly created remote account. The server is on AWS. I am connecting it via SSH Tunnel.

I have checked the database as well

select * from user \G;

and I can see the permissions as well

Solution

The database is mysql and I was selecting the dll of mariadb. That's how I made it work.
