Cannot connect to database remote

Hello,

I want to connect to a database remotely. So on the Database User page, I set 'Access control' to "Allow remote connections from any host".

But I can't connect to the database, it keeps rejecting mee. The firewall allows Mysql connections.

I don't know what else to check, other Plesk installations I have running are working fine with remote access.

OS: ‪CentOS Linux 7.1.1503 (Core)‬
Plesk version: 12.5.30 Update #48, last updated at Oct 10, 2016 03:40 PM
