Zabbix 4.2 and [Z3001] connection to database 'zabbix' failed: [0] FATAL

[coffeina]

I installed Zabbbix with PostrgeSQL database. I can login to main screen in admin Zabbix panel but: zabbix server is not running: the information displayed may not be current - info is displayed.
I checked:

cat /var/log/zabbix/zabbix_server.log

and saw that:

database is down: reconnecting in 10 seconds

You can check if there are valid values in ' zabbix_server.conf' file for DBHost, DBName, DBUser, DBPassword and DBPort parameters.

You was right @andirs. I change password and now I see some logs and montoring on my dashboard.
