Zabbix 2.2 CentOS 6.5 can`t connect to remote MySql database

[tmi]

Hello. I can`t find where is problem.

I am installed Zabbix server on CentOS 6.5.
Configure database on other CentOS server.
When connecting using mysql -u username -p -h ServerIP. I don`t have any problems, but when I try configure zabbix to use that database I got error:
Error connecting to database: Can`t connect to MySQL server on 'IP' (13).

Can somebody tell what can be a problem?
Thank you.
