Incompatibility of frontend and server database

[junior gonzaga]

Good afternoon guys I have a problem with the initial configuration of zabbbix, there is a message of incompatibility between the frontend and the bank, can anyone help me with this problem?

This message appears in the database configuration (I am using the postgree database and zabbix 3.0 on different servers)

(Cannot connect to the database.
Details
The frontend does not match Zabbix database. Current database version (mandatory/optional): 2030000/2030000. Required mandatory version: 3000000. Contact your system administrator.)

The database version for Zabbix seems to be old.
The database is automatically upgraded when you start the Zabbix server process.
Once the upgrade process is complete, it will be accessible from the web frontend.
