Nextcloud on CyberPanel

I’m trying to install NC on CyberPanel. I make it as I do with all other apps. VHost is set as for apps per sub/domain (P.S. - in CyberPanell installation going on sub/domain root folder, instead in /var/www/) and docRoot is as:

docRoot                   $VH_ROOT/nextcloud

instead of

docRoot                   $VH_ROOT/public_html

CLI install is as

sudo mkdir /home/nextcloud.mydomain.com/nextcloud
cd /home/nextcloud.mydomain.com
wget https://download.nextcloud.com/server/releases/nextcloud-21.0.0.zip && unzip nextcloud-.zip
sudo rm -rf nextcloud-
.zip
sudo mkdir /home/nextcloud.mydomain.com/nextcloud/data
sudo chown -R cyberpanel:cyberpanel /home/nextcloud.mydomain.com/nextcloud

However, now I have Internal Server Error page. What I’m doing wrong?
