Как исправить ошибку [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to MySQL server on '139.162.155.83' (13)?

Устанавливаю по инструкции ZABBIX на сервер по ssh
CentOS Stream release 8
NAME="CentOS Stream"
VERSION="8"

установил mysql-server и запустил

mysqld.service - MySQL 8.0 database server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

 Main PID: 16220 (mysqld)

В файле vim /etc/my.cnf.d/mysql-server.cnf
такие базовые настройки

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysql/mysqld.log
pid-file=/run/mysqld/mysqld.pid

установил репо

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-4.el8.noarch.rpm

почистил кэш
dnf clean all

установил фронт

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent

потом создал юзера

mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;
mysql> create user zabbix@localhost identified by 'zabbix';
mysql> grant all privileges on zabbix.* to zabbix@localhost;

скопировал schema and data

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix

в файле /etc/zabbix/zabbix_server.conf прописал пароль для юзера zabbix

запустил

systemctl restart zabbix-server zabbix-agent httpd php-fpm
systemctl enable zabbix-server zabbix-agent httpd php-fpm

но в логе вот такое
