    @karsten13 So I have been tinkering with the MMM-Hue module a bit and have replaced jQuery which seems to invoke XMLHttpRequest, with node-fetch, albeit the older version (2.6.1) of node-fetch, but it now returns data without requiring a certificate and the use of https.

    Check out my modules at: https://github.com/mumblebaj?tab=repositories

      The same problem appears to happen with MMM-Homematic. Getting same errors after update to 2.18.0

      Access to XMLHttpRequest at 'http://192.168.178.xx/addons/xmlapi/state.cgi?datapoint_id=1824' from origin 'http://0.0.0.0:8080' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space private.

          @karsten13 Its working now with:

          var config = 
          {
            electronOptions: {
          		webPreferences: {
          			webSecurity: false
          		}
          	},
            useHttps: true,
            httpsPrivateKey: "config/example.key",
            httpsCertificate: "config/example.crt",
            address: "localhost", 
            port: 8080,
          //  address: '0.0.0.0',
            ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.178.1/120", "192.168.178.100/24"],
            language: 'de',
            modules: [
          

          But with this setting, i have noc access the the RemoteControl-GUI and API also! ;(
          I really use it with my homeautomation to show/ hide modules.

          Is there another possibility?

            you must access the site with https, e.g. https://192.168.0.143:8080/remote.html

              There is now a new version available for MMM-Homematic that also works w/o changing the config.

                @carstend Yeah, was just noted, too, about the update.
                Some how I ran ino a problem when applying ‘git pull’, so I had to reinstall the module.
                First the screen remained black. so I hat to install manually the ‘request’ library manually (see https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later). Now it works!

                  @mumblebaj This is the new module I created. Does not require https.

                  https://github.com/mumblebaj/MMM-PhilipsHue.git

                  I am sure this will need to be changes once they enforce the headers stuff but for now it will work just fine.

                    @karsten13 said in MMM-Hue CORS Policy Issue:

                    @oberfragger

                    you must access the site with https, e.g. https://192.168.0.143:8080/remote.html

                    Unfortunatly its not working via https. Still connection refused. I dint think that https://github.com/CatoAntonsen/MMM-MotionEye will update after 5 years.

                      @oberfragger

                      can you access the mirror with https://<ip-of-pi>:8080?

                      May you are using a client which is not in the ipWhitelist? You can test this with setting ipWhitelist: [], in your config.js.
