How to add Access-Control-Allow-Origin header for lighttpd (Pi-Hole)

[0x3ronic]

I am trying to get the Pi Hole widget working in Dashy but I am encountering some CORS errors. How do I go about adding the Access-Control-Allow-Origin header for a lighttpd web server? As Pi-Hole is installed on my RPi and uses lighttpd instead of the ones mentioned here (https://dashy.to/docs/management/#setting-headers), I have tried adding the following line (10.10.69.13 being dashy):

setenv.add-response-header = ( "Access-Control-Allow-Origin" => "http://10.10.69.13" )

To the config file:

/etc/lighttpd/lighttpd.conf

After restarting, the errors are not resolved and it actually brings down my pi hole web server. Any ideas?

This is my dashy config:

• name: Pi Hole
  displayData:
  sortBy: default
  rows: 1
  cols: 1
  collapsed: false
  hideForGuests: false
  items: []
  widgets:
  • type: pi-hole-stats
    useProxy: true
    updateInterval: 20
    options:
    hostname: http://10.10.10.6/admin/index.php
  • type: pi-hole-top-queries
    options:
    hostname: http://10.10.10.6/admin/index.php
