error

• Connection to Zabbix server "127.0.0.1" refused. Possible reasons:
• 1. Incorrect server IP/DNS in the "zabbix.conf.php";
• 2. Security environment (for example, SELinux) is blocking the connection;
• 3. Zabbix server daemon not running;
• 4. Firewall is blocking TCP connection.
• Connection refused
