arch linux apache start at boot crash

I have Raspberry Pi B+ with Arch Linux installed and at boot time, apache web server does not start:

[xxx@rpi ~]# systemctl status -l httpd
* httpd.service - Apache Web Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

However, if restart apache from ssh terminal (after system restart and ssh login), the apache is ran properly:

[xxx@rpi ~]# systemctl restart httpd && systemctl status -l httpd
