GUI does not work after building Zabbix Server 6 from sources

[dimus]

I built Zabbix Server 6 from the sources (Ubuntu 20.04) and installed php and apache from the packages.

Apache is running (I get default Apache page on http://my_ip) but I get error 404 while trying to access http://my_ip/zabbix

I installed Zabbix many times from the packages (not from the sources) and I never had this problem

Zabbix Server itself and Mariadb are running

When using the package, the configuration is added to access Zabbix frontend content via Apache. Did you add those settings? Separately, build an environment of the same version using a package and compare it.
