Are you able to access 10.0.0.219? What does dig or nslookuppi.hole show as the IP address?
lighttpd is working correcly:

Do you have a setting in your browser which forces all http requests to become https requests? If so, turn it off or find where you can make an exception for pi.hole or 10.0.0.219.
For example in Firefox this is in Settings and called "HTTPS-Only Mode" and you can turn it off or turn it on but add exceptions.
