How to troubleshoot lighttpd service not starting up?

I am using Ubuntu 18.04.4 LTS. I have installed lighttpd 8.28. I have created the folder - r-x 2 www-data www-data 4096 Mar 16 15:41 httpd I am pointing my server.document-root to /home/httpd When I restart the service. # systemctl restart lighttpd.service Job for lighttpd.service failed because the control process exited with error code. See "systemctl status lighttpd.service" and "journalctl -xe" for details. I get the following errors on syslog. I am clueless on how can I debug this and what is the real problem here. I have changed the group to www-data for my server-document.root. Mar 16 16:28:42 abc-VirtualBox systemd: Starting Lighttpd Daemon...
